Re: [PLUG] kernel panic from unknown cause
|
Per a google search[1], there are numerous things you can do to debug but judging from that pastebin, it's either a bad kernel compile/image or it's bad memory.
Burn a sysresccd[2] and do a memtest (memtest at the boot prompt) and also do a badblocks test to check for bad sectors in your /boot.
Between the two, if everything's clean try booting in single-user mode. If that works, then it's a matter of an init script somewhere sapping all the memory allocation

Subject: [PLUG] kernel panic from unknown cause
My SME server (based on CentOS 4.5) had a kernel panic at 4:06 this morning.
How do I determine, if possible, what caused the panic?
Based on the first line of the relevant log entries ( SEE:
http://pastebin.com/m67b742be ) it looks like some kind of memory problem.
Log entries prior to this were several hours earlier and appeared unrelated
(DHCP leases)
I'll run memtest this evening when I take the server down.
The system has 384 MB of RAM and a 433 MHz Celeron (yeah, due for replacement
REAL SOON NOW.) Main disks are 2x 160 GB in a RAID Mirror - operating normally.
Google leads me to the same question in multiple places but no real answers.
TIA
Eric
