CentOS 5 Networking :: Server Hangs For A Seconds?

May 20, 2010

I have Centos 5 Installation with following Linux ipmpls.mobilink.net.pk 2.6.18-8.el5xen #1 SMP Fri Jan 26 14:42:21 EST 2007 i686 i686 i386 GNU/Linux. I have Nagios running on it for monitoring switches. It also runs postfix to give email alerts in case of a switch is unreachable. The problem is that the server hangs for a minute and returns to normal operation. During this period if a switch is polled it cannot be reached and hence Nagios shows the Flapping state on the switches. I need to understand as to why the server hangs

CentOS 5 Networking :: Connection Drops 10 Seconds After Boot / Fix It?

Jun 3, 2010

I have had this issue for a while on my centos 5.4 dedicated server with 1and1. If I reboot my system, my connection starts and then drops in about 10 seconds after the system has booted.I connected through the serial console and noticed there was only one thing that seemed suspicious while booting. named could not start for some reason. So my question is - are these 2 problems related? If not, what could be the reason for my connection to drop?At the moment the only way of getting the connection back up is by running dhclient. This works until the next reboot.

Ubuntu :: Boot Hangs For 60 Seconds?

Jun 17, 2010

I am looking to speed up my boot time; it is currently around the 2-2.5 minute mark from Grub to desktop (including about 15 seconds at the login screen while I type my password).

I have forced ureadahead to reprofile, and have rebooted a few times until the boot time is fairly stable/consistent.

No xorg errors and only one warning ((WW) The directory "/usr/share/fonts/X11/cyrillic" does not exist.)

However, dmesg reports the following:

Code:
...
[ 1.121369] Freeing unused kernel memory: 656k freed
[ 1.121926] Write protecting the kernel text: 4676k

[ 1.146159] udev: starting version 151

I had a problem where my system momentarily hanged for a few seconds. Sometimes when opened a window like Dolphin or when I made a window full screen, sometimes when clicking on the screen while watching a DVD or sometimes when I clicked on a button it just froze for a few seconds and responded.

I have fixed the problem by disabling "Processor Power Managament" in the Bios.

Ubuntu :: System Hangs For 15-20 Seconds After Login

May 1, 2010

Just installed Lucid Lynx on my Desktop and after logging in I would get a 15-20 second pause before Gnome appeared. I found many many potential solutions for this problem on the Internet but none solved it. Finally figured out that it was due to the system seeing a floppy controller when I have no floppy drive. I was led to this conclusion by the following two lines in my syslog (System > Administration > Log FIle Viewer > Syslog).

May 1 18:27:04 Desk-Ubuntu kernel: [ 34.636665] end_request: I/O error, dev fd0, sector 0
May 1 18:27:16 Desk-Ubuntu kernel: [ 46.813441] end_request: I/O error, dev fd0, sector 0

Note the 12 second delay when it tries to read again.

So if you are getting the pause and seeing the same thing your system log then ...

Enter your BIOS and disable the floppy drive Use sudo and edit /etc/fstab commenting out the line with fd0 in it

Hope I can save someone else the headache of hunting through the Interwebs and finding 5 different solutions none of which worked. Learning as I go with Ubuntu so I didn't even know how to carry out most of the "solutions" which required more googling. I am migrating from FreeBSD due to application requirements

Ubuntu :: Autologin Hangs At Shell For A Few Seconds?

Jan 20, 2011

I created a ubuntu distro that originated from ubuntu server and have an xserver installed with openbox and am having problems getting autologin working. I had slim installed and everything seemed to be working except as soon as the monitor went into sleep mode and I moved the mouse to get it back it just came up to the shell again. With that problem I decided to remove slim and go with NODM and that worked perfectly for what I wanted but I was messing around with a few other configuration stuff and when I rebooted everything was fine until after the splash when it would normally boot into X it would show the shell for a about 10 seconds before it would boot to X.

Fedora :: Flash Objects In Firefox - Hangs For 30 Seconds Or So

Aug 12, 2010

I'm having a few problems with flash objects in Firefox. When I load a page with flash - ..... for example - the flash object is just a grey box and firefox hangs for 30 seconds or so. When firefox finally responds again all that's left of the flash object is a black box. Does anybody know what the problem is? And even better - what I can do to fix it!

For background info - flash was working fine in F12 before I updated to F13. Used the install DVD for F13 to perform the update. I'm running F13 64bit with KDE, Firefox is showing Shockwave Flash in the addons list. Originally installed the flash plugin using the instructions from mjm wired:

Code:
[mirandam@charon Download]$ sudo yum install nspluginwrapper.{i686,x86_64} alsa-plugins-pulseaudio.i686
[mirandam@charon Download]$ sudo yum install flash-plugin I've tried removing those packages and reinstalling but no luck.

OpenSUSE :: Nvidia Settings Hangs - Whole Desktop To Freeze For About 5-10 Seconds

Oct 28, 2010

Sometimes, running "nvidia-settings" will cause the whole desktop to freeze for about 5-10 seconds, spike the Xorg CPU usage up to 100%, until the settings appear where everything goes back to normal.

Running "nvidia-settings" from a terminal does not show any output and restarting X does not help. Any ideas how to figure out what is happening, any places to look for log files?

I am using an up-to-date openSUSE 11.3 (64-bit), KDE 4.5.2, an NVIDIA GeForce 9800GT and the proprietary NVIDIA driver 260.19.12, which I installed manually following the instructions from

OpenSUSE Install :: Upgraded To 11.3, System Hangs Every 10 Seconds For Half A Second?

Jul 20, 2010

I upgraded from 11.2 to 11.3 and found that there was no 3d support with the "nouveau" driver for the nvidia card. Then I linked in the nvidia repo and installed the nvidia driver. After that I noticed I had 3d support but things were a bit choppy, regardless of compositing or other tasks running. It appears that every 10 seconds the CPU load shoots up (on all 4 cores) and during about half a second all other activity is postponed, including mouse clicks, window moves, animations etc. Using the system monitor watching the CPU load, I see a train of load peaks traveling from right to left, 10 second intervals. Also done a graph on "paged in pages", same pattern, peaks on 6500/s. 11.2 Never exhibited this kind of behavior. Since I haven't found any similar postings I thought that some leftover of 11.2 may be the cause of this and since I am not an expert I would welcome any suggestions on how to tackle this.ystem: quad core Q6600, 3Gb mem, GEforce 8600GT, etcFwiw the load peaks are doubled, meaning peaks at 0, 3, 10, 13, 20, 23 etc seconds

Server :: Running Cobbler On CentOS Machine Hangs?

Nov 16, 2010

Using the EPEL Repository, I went in and installed Cobbler to my DHCP/Gateway box.Everything went smoothly on the installation front. I went ahead and modified the cobbler settings file (/etc/cobbler/settings) to point to my server IP (same box), and then got tftp running properly. Now here's the problem.Normally, you need to run `cobbler check` to find issues and correct them. I run that, and all I get is blank. Nothing. It just hangs at the prompt until I kill it using CTRL+C.When I CTRL+C from the hanging, it states "cobblerd does not appear to be running/accessible"...

Code:
[root@PalaceRedirect ~]# service cobblerd status
cobblerd (pid 6991) is running...

CentOS 5 :: 5.3 Hangs While Remotely Copying Data Onto Server?

Jan 25, 2010

Problem : centos 5.3 hangs while remotely copying data onto this server.

I have A centos 5.3 x86 Version installed on Xeon Quad core , running on 8 GB DDR2 RAM, RAID 1 confgured on SATA drives. this was old installation copy and It has many more things running on it.Therfore, I can't just reinstall it.

I have setup SAMBA PDC + ldap on it. I encounter that system hangs when I copy data into this server from LAN computers.

My troubleshooting steps :

1. I have checked for network issue , My network works fine when I transfer data between other LAN compuers.

2. Even I have tried confguring seprate LAN....

3. I thought their might be some problem with my SAMBA configuration, therefore I did data transfer from sftp .

CentOS 5 :: 5.2 Installation Hangs On Server With Large Number Of Drives?

Apr 6, 2009

I am attempting to upgrade a system from 4.7 to 5.2 using a (now) DVD drive attached to the onboard IDE. Originally I had tried using a remote NFS image and a USB stick but I thought maybe there was a problem with the image. I can get up to the point of the installation of selecting the keyboard for the system and then it freezes and never goes any further. It doesn't appear to be a kernel panic since I can still switch between consoles.

I've got an MSI K9NGM2-FID with 14 drives in it. It serves as a file server for our backup server. It's got a secondary 4 port Silicon Image SII 3114 SATA card using the sata_sil module, and an old IDE Promise FastTrak TX2000. Technically I could have 16 drives but the 750W PS is walking the fine line on tripping it's self-breaker with the 14 drives and 7 fans. I would like to NOT have to disconnect all of this to do the upgrade.

I thought maybe that running the install using the "noprobe" option would help so it didn't detect and load the modules for the Silicon Image or the Promise cards and detect all of the drives but it still gets stuck on the step after selecting the keyboard. The installation info console and the dmesg console don't really provide any useful information. The installation console says:

INFO : moving (1) to step welcome
INFO : moving (1) to step language
INFO : moving (1) to step keyboard
INFO : moving (1) to step findrootparts

And the last lines of the dmesg console says:

<6>device-mapper: multipath: version 1.0.5 loaded
<6>device-mapper: multipath round-robin: version 1.0.0 loaded
<6>device-mapper: multipath emc: version 0.0.3 loaded

Is there a hidden "debug" option that will turn on a lot of extra logging?

CentOS 5 Networking :: Machine Hangs / Never Brings Down Interface On Downing Wlan0

May 20, 2009

I have managed to configure a wireles PCI card on CentOS 5.3 and it seems to work fine. It is a off brand (Hercules) with a Ralink RT61 chipset. I installed the most current driver (RT2501PCI/mPCI/CB(RT61:RT2561/RT2561S/RT2661) from the rt2x00 Open Source Project. I now have a question that might be very simple for one or more of you to answer. When I issue the command "shutdown -h now", the machine starts to come down and brings down eth0 cleanly, but when it attempts to bring down wlan0, the machine hangs and never brings down the interface OR powers off the box. The only way to complete the power off is to "hard" power off the machine.

Ubuntu Networking :: Server Randomly Times Out/Hangs/Disconnects

Jul 12, 2011

I have an Ubuntu 11.04 Server set up for my small office whose sole job is to run as a samba file server. The problem is that it randomly hangs. For example, I can connect the clients just fine, however if left idle it tends to take a few moments to work when you try to go back into the shared folder or drive. The client will behave like it is disconnected and is trying to search for the drive only to a few moments later, go right back to normal behavior.

If I ping this server while this is happening my requests will time out for a little while and then just start working. The same thing happens when I try to connect with Putty or through WebMin. One second its unreachable then the next its fine.I have already tried swapping out patch cables (which actually seemed to work for about 2 weeks) and I have patched it to an alternate port on the switch. The only thing I have not done at this time is to change the NIC.All the clients are running Win7 with the exception of two XP machines.Simply put, its like the machine just goes dormant for a while until you ping at it for a while to wake it back up.

CentOS 5 :: Udev Hangs After Upgrade To CentOS 5.4?

May 7, 2010

I have encountered the same problem as indicated in this post: "udev hang after upgrade from 5.3 to 5.4"[URL]... I'm testing the upgrade path to centos 5.4 on several virtual machines prior to upgrading our production systems. I have upgraded centos 5.2 --> centos 5.4 and centos 5.3 to centos 5.4. In both cases udev hangs after the upgrade. The following message is displayed on the console: "Starting udev: Wait timeout. Will continue in the background [FAILED]"

I found another related post: "udev hangs on boot for a long time, suspect pam_console_apply"[URL]..So, I booted by VMs using the "udevdebug" option to grub and received the same error message - "udevd-event [###]: run_program: Waiting ## seconds for output of '/sbin/pam_console_apply /dev/..."

In my /etc/ldap.conf file "bind_policy hard" is commented out. I added a line "bind_policy soft" as described in the post and my VMs booted fine. NOTE: This problem is not encountered with a fresh install of CentOS 5.4 and the "bind_policy hard" option in the /etc/ldap.conf is commented out as in the upgraded systems. What is really causing this problem and how do I get it addressed? I have a couple hundred systems to update from various releases of CentOS 5 to the latest current version 5.4. It would be nice to get this bug squashed..
