FreeBSD 8.2-RELEASE #0: Fri Feb 18 02:24:46 UTC 2011 root@almeida.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386
>Description:
We have some servers on different sites.
All servers have similar configuration and running software.
Sometimes servers hangs and don't respond to the keyboard events.
Servers can be rebooted by hard reset only.
At that time I can see the following on the console.
stack pointer = 0x28:0xfac3fb60
frame pointer = 0x28:0xfac3fbac
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 = 53151 (mediacnvr)
trap number = 12
panic: page fault
cpuid = 0
KDB: stack backtrace:

We have upgraded FreeBSD to 8.3-RELEASE but servers still hang.
