Red Hat Bugzilla – Bug 78934
System Hang for no apparent reason
Last modified: 2007-04-18 12:48:49 EDT
Description of Problem: This is my first bug report so forgive me for
Server was running fine for a few days. Came in after weekend and entire server
had locked up. Could not even get a shell to work. Had to finally press the
button. Checked all disks and everything started fine. This is what appeared
in the /var/log/message log file.
gandalf kernel:scsi : aborting command due to timeout : pid 4228797, scsi4,
channel 0, id 0, lun 0 Write (10) 00 02 07 d9 7d 00 00 04 00
That is the only line I can find that has anything to do with the hang. I am
sorry if that is not much help.
How Reproducible: Have no idea
Other Information: We did have a power failure over the weekend but both a
server and a workstation are connected to the extra power unit and the
workstation was fine. Neither of them had shut down. After rebooting the
server there appears to be absolutely no hardware failure at all.
Log files as attached
Created attachment 87249 [details]
/var/log/messages log file of server that hung
Looks like it just stopped talking. That could be a spike from the power surge
confusing something before the UPS kicked in. Its very hard to say.
There isnt enough good info here to go on so I'll close the bug assuming it was
just a funny of the power failure, but if it happens again please do re-open it
and we'll dig deeper
My system hung again in exactly the same fashion as before. This is the error
message I got from /var/log/messages
gandalf kernel:scsi : aborting command due to timeout : pid 13015122, scsi4,
channel 0, id 0, lun 0 Write (10) 00 00 8f 31 0d 00 00 08 00
I did notice that my load average shot up to around 14. My load average is
usually never higher than about 0.3.
I was unable to do anything. I tried to log in at a terminal but it never got
past asking for my username. I'm guessing that is because my load was so high.
There were no power failures or fluctuations that I am aware of (Unlike last time).
Again, not much to go on. Should I post a general overview of my system
