I have a new IBM x3650 that I am trying to get installed and running. However, it seems to experience random segfaulting. The system has ECC RAM and I have taken a look at the EDAC reports from the kernel, but as far as I can tell there is no error.This is a critical system I need to bring up, so I can't have it act flaky like this. Software is up to date. [URL]

I'm having some strange issues with apache. Time by time it segfaults, eats all available memory (including swap) and makes server non responding.Ubuntu Server 10.04.2 LTS
Some strange logs: Jun 12 12:00:18 *** kernel: [40767.969443] apache2[7635]: segfault at 726f7272 ip 00007f13a31f3f16 sp 00007fff6f740ea0 error 4 in libapr-1.so.0.3.8[7f13a31d7000+35000]
We administer a small lab of Ubuntu 11.04 machines. Users authenticate via NIS to the fileserver, which then uses NFS to mount their /home directory.
From time to time, seemingly at random, the machines will lock up. After about 15 minutes, they will go back to normal.
Switching the machine to the console with/ Ctrl+Alt+F1 doesn't help either - credentials get entered, but there's still a 15 minute wait before any commands can be entered. Some error messages show up at this point about processes that were running timing out. However, the root user can log in immediately (which makes us think that this is only affecting NIS accounts).
Logging in with the root account, we can ping our NIS server, and it responds normally. We can restart the networking and NIS daemons but neither of these help.
We checked the NIS error log in /var/yp/ypserv.log and it is empty.
We used to be running a different version of Ubuntu on the client machines (10.04 LTS), but not on the server.
I am running a headless Ubuntu 10.04 server with the 2.6.32-28-generic kernel. For what I can figure out no single direct cause I get a high load average and the following syslog output at random intervals. Generally the load average will drop back down to normal however the kernel errors will still continue What little I have been able to find has pointed to memory issues. I am not totaly convinced this is the cause as the server will be showing >50% free when the errors are happening.
I'm looking for a script that copies a random .jpg from a random folder in my ~/Pictures folder to my ~/temp folder with a standard filename. This file will then be displayed in Conky. I can fix the last part, but I cannot find a way to do the first part.
I'm having a very strange problem with my ubuntu apache2 server running wordpress. i want do download media files (from within a flash-mp3-player onsite or by link [url]) but the file transfer just stops after a while. (at least sometimes) at random positions. after that i have to clear the browsers cache and try again.
It is really annoying, though it is my band's website and we want to share our songs with our friends. i checked from several clients, seems to happen everywhere (linux, mac or windows clients)
On FC11 64 bit with Adobe flash plugin for Linux installed, I see segfault errors from "npviewer" in /var/log/messages. The only browser I have tried yet, Firefox, has glitches every now and then. Sometimes it shows the title of a page in a tab, but the page is blank. This can even happen when I try the Google main page. Is it true that npviewer has something to do with Adobe flash? Is there a way to fix the problem? If it is caused by Adobe flash, is there a different plugin that will replace Adobe flash player?
What is the easiest way to make it so that these transferred files will not be completely locked out and require me to go and change them one by one sohat i can access them without having to go root. Also the "apply to all subfolders and files" doesn't work. Also trying to set the SELinux rule to "userspace" doesn't do anything else. Basically i was trying to do just that transfer my $home folder over to fedora but now it's being a bit odd towards me with making everything require root access and not letting me read/write all files and folders within them.
I just installed Fedora 12. Now i've seen a few other threads but they seem to have all the conclusion that its the Nvidia drivers at fault. Well i have an ATI Mobility Radeon 3400 series. I can login, and navigate for a little bit, then it just randomly freezes. I've booted to both gnome and KDE, kde freezes almost immediately w/o letting me navigate much. Gnome takes a bit and then freezes on me. I managed to login once and go like 6 minutes then i thought it was worked out, rebooted and boom, froze up again. I can still move my mouse but can't click or use keyboard. Ctrl+Alt+Backspace doesn't work either .....
About a week after I installed F12 on a brand new system, a friend came over and went on to play poker on facebook. At some point he yelled that the PC froze. I was working on another machine at the time and tried to ssh to the supposedly hung system, but couldn't; Except for playing poker he had audacious open and about 3 seconds of the song that was playing at the time of the hang, kept looping. Neither Ctrl+Alt+Backspace nor any of the Alt+SysRq combos had any effect whatsoever, so I had to press the reset button (and I have to say this was the first time I had to do so in linux after almost a decade of using it, save for a hiccup with my first gentoo kernel).
The system usually freezes if there are two or more sound streams, but that is not always the case. The best way to get the system to crash is by playing something in audacious or rhythmbox while seeking through a video in mplayer or vlc or having flash content appear in firefox (I am using adobe's latest 64-bit flash plug-in and have been using it without any problems -though on other systems- since F10). Also most but not all the times the system is going to hang, there are a few skips in audacious every ~10-30 minutes. I've been getting the lock-ups with every kernel released so far.
My system logs don't contain any useful info after each hang; there are however certain problems mentioned in syslog which I thought they could be relevant, but they always appear whether the system works fine or not, namely the following:
Code:
I used to get a lot more of these with previous kernels:
Code:
Code:
This one appeared every now and then until Dec 25:
Code:
And this one is always there:
Code:
Finally, at every boot I get this from abrtd, but it doesn't seem to be related:
Code:
Yesterday, I devoted the entire day to hunting down the culprit, but I couldn't get the system to hang; I had rhytmbox, audacious, totem, vlc, mplayer and vlc all playing music and videos simultaneously from local disks, network shares and through upnp, I got myself a facebook account in order to play that zynga poker thing, I upgraded alsa-lib to 1.0.22 from updates-testing, rebooted countless times, but the system didn't hang nor did any of the above messages disappear. Today as I was browsing through some web pages, one of which had an interactive flash ad, while listening to music and the system froze again.
So MPD keeps segfaulting everytime it tries to play anything.I tried compiling a version from the MPD site, but that couldn't even see my music for some reason. Same user running MPD, same permissions on the files... I'd really like to get MPD working again, but it keeps segfaulting with this:
Code: nas kernel: [161048.253573] mpd[22957] general protection ip:b6efc1b5 sp:b53e1850 error:0 in libavcodec.so.52.20.1[b6ab4000+52b000]
I wiped my server recently because of all the custom stuff I had installed, and now MPD won't play music .
This just started today, after I installed a round of updates yesterday: I would attempt to login to my GNOME session. One of three things happens: it hangs, looking like it's authenticating, it lets me into my session but then abruptly logs me out and wrecks anything I was doing, or GDM just crashes altogether.
On tty6, I found this error in dmesg:
Code: gdm-session-wor[1392]: segfault at 1 ip 0000000000000001 sp 00007fff57babe18 error 14 in gdm-session-worker[400000 + 17000]
The numbers may be slightly off, I had no way to copy and paste the error. I have no modifications to GDM except libpam-usb, which doesn't even work. Is it possible to roll back GDM to before the update?
I have some curious errors and crashes since yesterday. Firefox crashes without saying anything or just freezes. Thunderbird also crashed once without any reason, as far as I could discern.
Compiz is another candidate. Either it segfaults and sends me back to the GDM login screen or it crashes in another way, resulting in a flickering window with an unreadable error message (just an empty window with the nautilus icon in the menu bar, background image stays the same, Unity or any other compiz things are gone). I even had some real X segfaults mixed in.
I've installed fedora 11 (GNOME) on my laptop. It sometimes reboot itself. The screen goes black and reboots(sometimes just turn off!) Palimpsest Disk Utility reports HDD bad sector but when I run memtest, everything looks fine. Windows xp does not have this kind of problem before I use fedora
I've installed Eclipse PDT with yum and httpd got installed as well. The problem is everytime httpd starts it chooses different (random) port and refuses connections to other ports like 80 (displays 403 forbidden error). That's really annoyng because I have to launch eclipse and open file in "PHP Browser" to get the right port. It also makes me unable to setup vhosts properly (i think). How to force apache to stick to the 80 port? Heres my httpd.conf: [URL] The only things I've changed there is added vhost
In LMMS, pretty much any time where pressing a key or button is supposed to do something, it can crash. Regardless of what made it crash, it always dies in the exact same way: The window just disappears, and I get the line "Segmentation fault" in the console. Usually it crashes within 15 minutes of normal use. Not even 6 hours after I downloaded the program, I had given up trying to use it. Over the next week, a couple other programs crashed with segfaults.
Most of them only crashed once (among those was Firefox). So, of course, I'm now beginning to think that maybe the problem is not with LMMS, but rather with Ubuntu. I've had very little luck getting most of these programs to crash a second time, but I did find reliable ways to reproduce the crash in LMMS and Golly, so I got debug logs of those (with backtraces and steps I took to reproduce):
Code: What I did to make LMMS Crash: 1. After starting LMMS, created an instrument track using the Oh Synth preset (under LB302) 2. Opened the tool window for the track. 3. Dragged my cursor back and forth across the keys on the virtual piano at the bottom of said window to play them. 4. Within 3 seconds, it crashed.
Code: What I Did to make Golly Crash: 1. After starting Golly, loaded the example file "Still-Lifes/eaters.rle". 2. Alternated between Space (Next Generation) and Ctrl+Z (Undo), holding each for about 1 second. 3. Within 15 seconds, it crashed.

I've tried using different governors for CPU (Conservative, Ondemand, etc.), and these crashes continued to occur. I also tried using a different kernel to no avail; the crashes occur both on 2.6.32-21-generic and 2.6.31-17-generic. How to fix whatever's causing these segfaults.
Running Maverick Meerkat fairly close to original specs. When launching Rhythmbox from either the command line or the applications menu, the window appears briefly and closes whether or not I interact with it. During its time open (~3sec), it gives no indication that it recognizes input, i.e. menus do not open and buttons do not depress when clicked.
While running from the terminal, the following output is displayed.
I upgraded my processor two days ago(p4 -> C2D), and ever since then I have been getting segfaults, which are causing my programs to crash randomly. At first I thought it was isolated to one program(deluge), but after searching around I was looking at the /var/log/messages and found a bunch of segfault messages after I installaed the processor. Here is the grep from the messages file:
Code: Nov 29 12:35:03 Thor kernel: [66065.114231] npviewer.bin[14952]: segfault at 0 ip 00000000f6232ed1 sp 00000000ffe9e6d0 error 4 in libflashplayer.so[f5e93000+b2e000] Nov 29 12:41:23 Thor kernel: [66445.260799] npviewer.bin[15324]: segfault at 418 ip 00000000f60ddc86 sp 00000000ffb4b928 error 6 in libflashplayer.so[f5e8e000+b2e000]
I'm using Red Hat Enterprise Linux Server release 5. In this whenever a user process crashes due to segmentaion faults , it was not logged in /var/log/messages. Even dmesg is also not showing any messages related to this.
Where as in another distributions(Cent OS 5) I've seen segfaults messages in /var/log/messages whenever my user process crashed.dmesg also showing the segfaults.
Is there any settings that to enabled so that it logs segfaults into /var/log/messages.
I cross checked /etc/syslog.conf of both the systems. Both are same and even /etc/sysconfig/syslog files.
I googled around but most of what I could find said that segfaults are generally a memory issue. I've noticed lately that I'll occasionally get a segfault while compiling on my computer. There's no noticeable pattern, just that every now and then a bit of software that I'm trying to compile will segfault on me, even software that I've compiled in the past.
I ran memtest86+, but it showed no issues at all. I run a stock kernel on Slackware, with no modifications to the system other than installing multilib support (which I'm 100% sure is done correctly).
I'm having a slight issue with apache segfaulting reasonably regularly. I've followed through the apache http debugging guide here:[URL] and receive this when running gdb:
Code: [root@ukserv1 apache2-dump]# gdb /usr/sbin/httpd core.1085 GNU gdb (GDB) Red Hat Enterprise Linux (7.0.1-23.el5_5.2)
New install slackware64 13.0. Sites that cause it to segfault are simple ones - gmail (2 seconds after I get past the sign in stage, and before I even open any email. This one also www.channel4.com/programmes/4od.
I have done the obvious stuff - checking for missing libs with ldd, finding them, etc. Disks are 1-2 years old (ext3) and well checked, but this install has not been lived in yet. Plugins installed are: java 1.6.0_16; Flash 10.0 r45; SVG-2.26. Kernel is 2.6.33.2, made with 'make oldconfig from a very satisfactory 2.6.30.5 kernel which was faultless for some time.
The box is all-amd/ati HP6715S, with RS690 video and northbridge, sb600 southbridge. and a twin turion 2 Ghz. It is using the recent OSS xf86-video-ati drivers. The only strange Mozilla error was between 4th and 5th crash this session when it said "Input/Output Error". Otherwise the error shows as line 131 of run-mozilla.sh - the 'finally start the binary' routine.
It's been freezing on me like you wouldn't believe today, and I think it has something to do with the load put on the CPU by various sites. The trouble is, I need to access a few of these sites to do my work. WordPress is one of them. I've had to restart the computer five times via SysRq keys since when these freezes happen, I can't Ctrl-Alt-Backspace out of it (even with zap enabled) and I can't bring up a terminal or Alt-F2 to kill process. I can't switch processes, windows, or anything. Firefox just sits there and laughs at me as I threaten to bust the screen in half.
And the real funny thing is, people actually say this is a better browser than IE. I never had these problems on Windows.What can I do to stop this? Do I just have to switch to another browser?
I am using Fedora 12. I am able to connect to my wireless network (95% of the time at least) on start-up automatically, however after anywhere between a few seconds to a few minutes later it cuts out and will not reconnect. It appears to be that whenever it finds next doors network it disconnects from mine! I have set the channel to 9, and my neighbor's is on 1. I have a USB N+ adapter, and a G+ MIMO PCI card, however do not know which is being used to connect with.
My firefox (Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.6) Gecko/20091216 Fedora/3.5.6-1.fc11 Firefox/3.5.6) on Gnome 2.26.3 will randomly crash, without any errors. /var/log/messages & /var/log/Xorg.0.log doesn't show anything that caused any errors. And it doesn't matter on which website(s) I'm busy with, it will just crash.
My PC has:
Intel Pentium(R) Dual-Core E5200 CPU 4GB DDRII Corsair RAM 3x 160GB SATAII HDD Asus Nvidia 8800GT graphics card.
This is on Fedora Core 12 x86 I have disabled the only 3 Firefox plug-ins that I installed yesterday, but this problem has been looming for a long time. Something interesting that I picked up is that Thunderbird will close randomly (very seldom though) as well, so I don't know if it's Firefox specific though.
I have picked up that it happens more often when my PC's memory usage is above 2GB RAM, and memtest86+ didn't indicate any memory problems. If I have less tabs open, it happens less often, but the more tabs I have open, the more often it happens. At the same time, on the same PC, when I'm in Windows XP SP3 (dual boot), I can have many more tabs open as well as Thunderbird, Quickbooks, Photoshop CS3 and some other applications, and it doesn't cash.
I just installed 64 bit Fedora 12 on a Dell Latitude E6510. When I am typing, the cursor sometimes jumps to a random place. This is very annoying, especially while coding.
This was not a problem with Fedora 11 live or Windows 7 (dual boot).
I'm getting very random full system freezes with F13. The keyboard stops responding completely. Sometimes the mouse (and the mouse only) still works. I those cases, I can log in via ssh, kill kdm, and everything goes back to normal until the next freeze. However, in most cases, I have to do a hard reboot. Sometimes the system goes on for days without a problem, and sometimes it freezes 10 times in a day (It's in one of those days that the bug-screen saved me from flying out the window). I also had this problem on F12. I'm not sure if its video-driver related as both nvidia and nouveau experience this behaviour. In fact, I'm not at all sure what the cause may be.
