Crash Dump

[Jack L. Stone]

FreeBSD sage-american.com 4.8-RELEASE-p13

Hello again. Hope this the place for this question.

One of my mail servers has been crashing for several months about once
every 2 weeks at random times and after changing out all hardware,
including shifting the OS to 3 different machines, I finally concluded it
was the OS and setup to catch a crash dump. The dump is submitted below and
perhaps someone knows how to tranlate it for a recommended fix. If this
should be on another list, please let me know.

Thanks for any help!
