Hi Folks,

   I've been running repetitive 'make release's on a box
and it died once (no serial console), and I finally got
it to crash again after about 2 days.

uname: (world and kernel up-to-date as of)

5.0-CURRENT FreeBSD 5.0-CURRENT #0: Thu Oct 17 02:12:59 GMT 2002

Basically, I reload the source tree (inside of make release)
from the nfs mounted repo. The box itself is a single processor
amd system running a uni-processor kernel.

Follows is a backtrace and process dump.

I've restarted the process. Any ideas for where to head with
this are welcome. I'll be glad to do a deeper debug session
on the next crash.
