Ubuntu :: 10.04 LTS Server Hanging During Bootup?
Sep 14, 2010
I seem to have the following problem with Ubuntu. I have two PATA drives in my server. The OS is loaded on the first drive which is the master and the server functions fine. This is what I want to do is to have two 120 gig drives in the system and mirror them. When I put the second drive in set to be a slave the bios see's both drives. After the bios shows what is in the system it hangs with the cursor in the upper left hand corner and will not boot beyond that point. If I unplug that second drive it will boot up with no issues.

When I went to start up the computer, the kernel usually hung at the same place on boot up, although sometimes it booted just fine. The default kernel is 2.6.31.9-174.fc12.x86_64. It's boot up arguments are:
Code:
kernel /vmlinuz-2.6.31.9-174.fc12.x86_64 ro root=UUID=75d16864-ba74-49ef-aaa9-0a1dd3c92254 noiswmd LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us rhgb quiet rdblacklist=nouveau
I also have kernel 2.6.32.7-37.fc12.x86_64, 2.6.31.6-145.fc12.x86_64, 2.6.31.5-127.fc12.x86_64. I have seen the same behavior out of all four of them. Last night I ran Memtest86+ all night. It took eight passes with no memory errors. As far as hard disks go, I have two Seagate Barracuda 1.5 TB drives operating as software RAID 1 (mirroring). One of the drives does have three bad sectors. The motherboard is an Asus P6T6 WS. This morning I plugged in the GP diagnostic chip that came with it, but I'm not seeing a whole lot useful there, except that now it is just displaying "FF" non stop.
I did some poking around on the web, and it looks like "FF" is supposed to mean that the CPU isn't properly seated, which makes no sense because the system monitor software is detecting all four cores perfectly, and I have no other odd behaviors anywhere else. At this point I'm rather at a loss to understand what could be causing the difficulties. Sometimes any of the four kernels boots fine, and sometimes they don't. The funny thing is that on the blue "boot progress bar" all four kernels hang at exactly the same spot if they hang at all. After doing some more poking around, I'm relatively sure that "FF" does NOT mean that the processor isn't seated correctly. I'm going to try contacting Asus and see how far I get towards getting some good info on what the diagnostic codes mean.

Our mail server keeps on hanging after a while. This happened after there was a breakdown in electricity supply and the server room air conditioners stopped working for almost half a day. We are not sure whether this is a server hardware problem or a coincidence with a break-in attempt or malware activity.
Following are the message from the server log code...

I've got a server running CentOS 5.5. I used the automated iptables config tool included in the operating system to allow traffic for vsftpd, Apache and UnrealIRCd. When I send large files to FTP, even from the local network, it works fine for a while and then completely times out... on everything. IRC disconnects, FTP can't find it and when I try to ping it I get "Reply from 10.1.10.134: Destination host unreachable" where ..134 is the host address for the Win7 box I'm pinging from. This is especially frustrating as it's a headless server, and as I can't SSH into it to reboot I'm forced to resort to the reset switch on the front, which I really don't like doing.
Edit: the timeouts are global, across all machines both on the local network and users connecting in from outside.

I recently moved my site to a new server (Apache 2, PHP5, MySQL5). The site is an Invision based forum. Every few posts / topics it just hangs. The data has been written because if you stop and reload, the post / thread is there. I thought it was a write issue initially, but nope. So, the data is written but the page load never completes. It doesn't leave the page where the data has been input.
Whats the best way to trouble shoot this issue? The only thing I have done recently is reduce my MySQL timeouts, but I can't see that being an issue as the values are still big enough and there are no mentions of timeouts in the MySQL log. (For the record there is nothing in PHP's error log either)
I have checked my server-status. It all looked ok, but I have a suspicion I was hitting my ServerLimit, so I doubled that. Also enabled my Keepalives. Will keep an eye on it.
Some additional info;
1. Apache is throwing seg faults, but enabling core dumps does not produce them.
2. I have tried disabling the modules in apache but it just stops things from working.
3. I fear it may actually be DNS related. If I watch Live Headers in Firefox, absolutely nothing happens during this 'hanging' period. After that, the responses come back fairly promptly.

I have a service I've made an init script for, and it's added to chkconfig, which shows it "on" in all the correct runlevels. When I start or stop this service using the "service" command all is fine, but it does not start on it's own at bootup. I am currently at a loss to determine why it is not starting. Here is the script:
#!/bin/bash
# chkconfig: 2345 95 10
# description: Start or stop home automation

What is the best method for debugging the booting process? Is there a cheatcode (tried debug and failsafe). Slackware 13.1 with standard linux kernel 2.6.35.8. I having a problem with a dell server 2860 booting my build. It is hanging on
[Code]....
Booting my previous kernel 2.6.27.27(different disk with different initrd.gz) it loads the same as above but continues with
Code: loading iSCSI transport class v2.0-870 iscsi registered transport tcp I'm stumped it the problem is with the ata_piix module or the iSCSI transport module or some firmware I might be missing. I booted other pcs without issue.

Problem I have is the Samba server, it does not seem to start up the shares at boot.When I boot the system, nothing is available on the network, I have to run the Samba Server Configuration Tool everytime I want to access a share, edit a share, save and quit, then my network shares become available.I see Starting SMB services during boot up, it says OK.It worked good on Fedora13.

why I'd be receiving this error. I have created a partition and filesystem and put the label in fstab. Everytime I reboot the server it is unable to mount the filesystem. However I am able to mount it manually.

Since upgrading to Lucid, I am getting the following dialog warning on login: 'Could not apply the stored configuration for monitors X Server does not support size requested' Im using the current proprietary NVIDIA graphics driver with dual heads. My display is fine, but the warning every time I login is annoying. After googling around I found this thread: [URL]. I tried going to Monitor Preferences as suggested. My resolution as displayed in the default tool is set to 3840 x 1200, which I suspect is the issue forcing the dialog, but I cant change the resolution, refresh rate or rotation from the Monitor Preference dialog box. dino99's response (in the referenced post) about xorg.conf not being needed anymore seems relevant. How can I resolve this issue and get rid of this annoying warning? Is there a configuration that I can update with a supported resolution to placate lucid?

Using the latest version of Ubuntu. Trying to ftp to an ftp server. Able to successfully login through terminal but when I try and list the contents of a folder I get "200 PORT command successful" and then it just hangs. I thought it might be the server but I've tried it on different Mac and Windows machines and was successful. I can only assume there's something in Ubuntu which is blocking it.

I am running Ubuntu 9.04 on a wireless networked host machine. The wireless NIC is usb based. Its running inetd for network based servers (telnet, ftp etc).For some reason telnet, ssh or any application specific connection, hangs for a few seconds and then comes back. This happens after every few minutes. I do not loose any sessions or any data flowing across but it is sort of very annoying.It is a dual boot machine and I have also got Windows XP 64-bit. When am running on windows this does not happen, hence am not sure if it is something to do with the wirless nic or something else

There's a strange problem, after installing ubuntu 10.04.1 using wubi.
The installation goes fine in Windows, unpacks to an empty 15gb ntfs partition. After restarting to complete the installation, it would'n find the grldr but fixed that by copying over the wubi* files installed in C:.
Now the problem, the boot screen shows for a few seconds, switches to the default ubuntu wallpaper, the mouse cursor is there and working, and that's it. The installation doesn't continue, the keyboard won't work; Also I've tried all the additional options the installation offers when it asks to press Esc.
The system:
Wubi installed size: 15gb
32bit Ubuntu 10.04.1
4gb installed ram
nVidia 9800gx2
Using ubuntu for a month on my netbook determined me to add it to my desktop so I hope this gets fixed

Most of the time when using USB flash drives under Linux, the OS will lock up at 100% IOWAIT, with a load average of 12-18. Even my music stutters and stops. Using USB drives makes my Core I7 3.0GHz HyperThreaded act like a Pentium 2 running Vista. It's embarrassing. A client asks for a file, and it takes me 2 hours to copy it. This is a deal breaker. I've been trying to find a solution. If I can't, I'm sorry to say I'll be leaving Linux for something that can use USB drives. I've been using Ubuntu for 4 years, I'd hate to leave. Don't take that as threat, just a stark fact based on business decisions.

a few weeks ago i installed Ubuntu 9.10 on my PC on which i was previously using Ubuntu 8.10. However after the installation of the new version, my machine keeps hanging all the time,like i can use it for 20 minutes and it hangs and completely freezes, so i have to force a shutdown in order to restart and it does so very often, i don't know where the problem really is. The PC is Pentium 4, 40GB hard disk, 512MB RAM, processor speed of 1.8 GHz.

I've read the various Grub2 posts and even the guide, but unfortunately for me I can't seem to come up with an answer to my problem. I installed Ubuntu 9.10 on a new hard drive on a friends laptop, but I have problems with the system hanging on the Grub2 bootup.I'll post the screen
recordfail=1
if [ -n ${have_grubenv} ]; then save-env recordfail; fi
set quiet=1
insmod ext2
set root=(hd0,1)
search --no floppy --fs-uuid --set ac1b1d46-bac1-4140--953e-70a8a61be8b0
linux /boot/vmlinuz-2.6.31-14-generic root=UUI=ac1b1d46-bac1-4140-953e-70a8a61be8b0 ro quiet splash
initrd /boot/initrd.img-2.6.31-14-generic
If I hold down the left shift and then press E to edit and remove the search --no floppy line entirely then press ctrl-x the system boots just fine. I then opened up a terminal and did sudo update-grub to try that but it didn't fix it. Is this a problem in my bios looking for a floppy, I tried with the boot from floppy enabled and disabled (but always as the 3rd boot option) the floppy is not installed. Is there anyway to edit the file and save it so it will boot up? I was trying to research that and could not come up with it.

My problem is with the new Ubuntu 10.04 Installer, and the Plymouth Bootloader.
I have installed Ubuntu plenty of times before on my hardware setup, so 10.04 shouldn't be significantly different, however I can't seem to get it to go past the purple screen with the red dots.
If i let it sit there for a while, then press an arrow key, it takes me to the text which is as follows:
Code:
(process:404) : GLib-WARNING **: getpwuid_r(): failed due to unknown user(0)
unable to open '/dev/mapper/nvidia_afgjfcea'
unable to open '/dev/sda'
unable to open '/dev/sdb'

I'm running a fresh install of Lucid without any issues thus far. I have my computer setup to log me in automatically, without requesting a password.
I installed Gnome-do and set it up to run at login (as I always have). After a reboot, my system is not responding to input from my mouse or keyboard. I can move my cursor, but it will not accept input.
I see gnome-do, which is partially covered by the "Unlock keyring" dialog" (which always comes up, I think to unlock my wifi).

I came home, having left Evolution running all day, to find it frozen and unresponsive. I killed it, opened it back up... and same thing. It opens, checks through my folders (I have one imap account, and one MH folder that Evolution dumps my pop mail into.) and freezes.
In the status bar, when it freezes, this is what it's doing:
Opening folder mh:///home/katia/mail;command=ssh%20-C%20-l%20%25u%20%25h%20exec%20/usr/sbin/imapd#inbox(...)
And then it just hangs.
If I disable my MH folder real quick, it doesn't hang and I can use my imap account fine. Re-enabling my MH folder quickly causes the hang again.
I tried opening the MH folder in clawsmail, but it hung also. Mutt was able to open it fine.

I recently installed Ubuntu Desktop Edition 10.10 . Everything works fine till the wifi is switched on. It keeps blinking and seems to work sometimes and intermittently hangs the system. Plus the machine hangs while shutting down whenever the wifi is turned on. I tried out acpi=no, pci=noacpi .
Note:I was also getting rt2800_pci_MCU_Status related hardware error and then added rt2800 to the blacklist.cfg , but this does not seem have affected the wifi and the hanging issue.

Ubuntu hangs after the lock screen menu disappears. When it goes into the lock screen and the menu disappears Ubuntu stops responding. Moving My mouse or typing on my keyboard doesn't help. The password screen does not appear. It does not appear to be this bug: as it stops responding within a second of the screen disappearing. I have confirmed that nothing is wrong with my monitor or video card using my brothers setup.
