I have the same problem on news server.

Configuration:
FreeBSD-2.1.0R
486DX4-100, 64 Mb RAM
AHA-2940UW, 4 Gb ST15230N, 4Gb ST15150W, 5Gb Wangtek 9500DC Tape

Periodically (2-5 days) server is rebooted spontaneously (basically during
back up). If I do
dump 0f /dev/null /dev/sd0a &
dump 0f /dev/null /dev/sd1a &
the system crash during 5-7 minutes.

This is a big problem for me.
