I've got a box that I had to reboot this morning because of a page fault.
Here's the system:
ASUS motherboard
Athlon 1.1 GHz
768 MB RAM
SCSI RAID (on a dpt decade raid card :( ) with (I believe) 4 disks.
So: postmaster 'crashed' as a result of a page fault in the system. A PG
process was still left 'running' although you couldn't kill it. So I
reboot. fsck complains, it gets fscked and fixed, comes back up. (and
before I rebooted it, I tried to fsck a partition after I unmounted it -
fsck seg faulted, page fault).
Syslog doesn't show any drive or swap errors (Are swap errors logged to
the syslog?) so I'm guessing right now that it's RAM. The RAID card isn't
barking, so I know it's not a failed drive. Could my swap partition have
become corrupted? Should I, late at night, do a swapoff and then
re-format the swap partition? Run a badblocks check on it? I need to know
what this is, but I don't have these problems very often, especially with
this hardware configuration (specific SCSI card, etc). My coworker is
pretty much sure it's the SCSI disks, but of course, doesn't know which
one, and says that a swap error won't go to the syslog (i.e. a bad block,
or something). Yet, it can log the page fault, so...
Any help would be neato.
