>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.

 This looks similar to the issue fixed in 9.0 (r227207 + r227449).
 
 There was a discussion on freebsd-net@ titled "Kernel panic on FreeBSD
 9.0-beta2":
 
   http://lists.freebsd.org/pipermail/freebsd-net/2011-September/029858.html
 
 Are there chances that you can check >=9.0?

 We use our software on FreeBSD 9.X without any kernel panics for a year.
