freebsd stable - Feb 2004 - FreeBSD constantly crashing

Hello,

I have one FreeBSD server, that recently started to behave strangely.
It has been rock-solid for all of its existence (almost 2 years).
Recently I upgraded it to RELENG_4_9 and it started crashing with
kernel panic approximately every 24 hours, but this varies.
I have tried downgrading to RELENG_4_8 and RELENG_4_7 - the same
thing keeps happening. I have also moved the harddrives in a brand
new, albeit identical machine - Duron 800 MHz, 512MB RAM,
Adaptec 29160 Ultra 160 SCSI, two Fujitsu disks in Vinum RAID1.

Here is the kernel panic:

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x485974e2
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc01cbfe3
stack pointer           = 0x10:0xc0311854
frame pointer           = 0x10:0xc0311858
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         = Idle
interrupt mask          = 
trap number             = 12
panic: page fault

attached are the kernel configuration and the dmesg.
Please, can anyone shed any light on this? I thought it was the hardware,
but I've changed everything except the hard disks - new case, new
powersupply,
new motherboard, new processor, new RAM, new Adaptec.

Thanks in advance.

It's not that - the RAM has been changed at least twice.
And this particular version of qmailadmin is just buggy, it has crashed
before on other machines also (some with Linux, some with FreeBSD).

The answer seems to be in your dmesg. 

pid 28555 (qmailadmin), uid 89: exited on signal 11

...that means you have bad ram in your new computer. It's common
for computer stores to sell ram that is less than perfect. Replace the
ram and you should be fine.

I saw problems like this when PAE was crashing my box in the early version
of 4.9. I would assume the patches were put into RELENG_4_9, but maybe you
want to try RELENG_4 to get -STABLE?

I know this doesn't explain why it is crashing in 4.7 or 4.8 though. Just
a thought.

Are you able to get a crash dump, or compile in DDB and get a stack trace?
Does seem odd that the problem would persist after a downgrade -- can you
confirm that you don't have any kernel modules that are out of sync with
your current kernel source?

I was install FreeBSD 5.2 on Hewlett Packard : Intel Xeon Dual Proc PIII 550
Mem 256, the drives are Seagate Cheetah 9,1 GB ... no RAID involved, its
just straight drives using the motherboard's onboard SCSI controller
AIC7880, I have found error on SCSI SCBs by default boot only, but I can
install successfully on safe mode, non ACPI, etc. So I am rebooting my
server, but I till found a error on defult boot only. I've tried to
recompile kernel, but no defferent... so still error...

Here is the problem, I'm having :

Kernel Free SCB list : 8, 9, 13, 12, 11, 10
Untagged Q(3) : 16
Untagged Q(4) : 2
Untagged Q(5) : 3
Untagged Q(6) : 4
Untagged Q(8) : 17
Untagged Q(9) : 18
Untagged Q(16) : 19
Untagged Q(11) : 0
Untagged Q(12) : 1
Untagged Q(13) : 18
Untagged Q(14) : 17
Untagged Q(15) : 16

<<<<<<<<<<<<<<< Dump Card State
Ends >>>>>>>>>>>>>>>>
Sg(0) Addr 0x222000 : length 36

Can someone tell me whether or not this is indicative of a hardware, or 
software, problem? 

Thank's

Is this a NetServer or a Compaq?  I've run FreeBSD on several NetServers
without problems.

This is some sort of SCSI fault. Check cables and termination, and any
messages output before the dump of the card state.

Probably hardware.
