Hi!

For the last few days I'm expiriencing a strange crashes: when I try to
cvsupdate+portsdb ports tree I get the weird errors and machine crashes
(automatically rebooted)

One I got this error:
panic: ufsdirhash_lookup: bad offset in hash array.

This time I got this one:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x3c
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc0309bca
stack pointer = 0x10:0xcda58bf8
frame pointer = 0x10:0xcda58be8
code segment = base 0x0, limit 0xfffff, type 0x1b
             = DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 1951 (make)
interrupt masks = none
trap number = 12
panic: page fault


The system is Athlon 700 MHz, 256 MB ECC RAM, 2 Seagate IDE disks (40 and
80 gigs), 1 SCSI Seagate disk (36 GB).

First I suspected that a power suply is malfunctioning, so I've changed
it. Didn't help. though.

I ran soime fsck on drives and it seems that disks are OK.

What could possibly be so wrong? The machine is online for about a year
and it worked fine till now.

Is there a possibility that a memory chip is dead (or should I say
deadish)?


Thanks for your help!
