>Description:
I have an urgent problem with three of our
webservers (PL DL140), running FreeBSD 5.3-STABLE.

These machines are running on a fairly simple,
configuration, ipf, Apache 1.3.33 / PHP4.2 / MySQL 3.23 / Postfix / Amavis etc. Nothing fancy. However I get some random crashes, even coredumps (dumpdevice)/ kerneldebugger aren't working! I have to manually reboot the servers on location. The last error msg I got was:

Fatal Trap 12: Pagefault while in kernel mode
CPU ID=3 APIC ID=07 While in kernel mode
CPU ID=1 APIC ID=01

..

Fault code = Supervisor read, page not present
currentprocess 613 httpd
trap 12

Anyone know a solution or have any tips to
increase robustness of the servers?

Disabling HTT in bios, APCI in FreeBSD and/or SMP doesn't resolve these problems.
>How-To-Repeat:
Leave server running in a production environment.

NA
