Hello,
i have strange problem on one of my FreeBSD 9.1 install.
The server randomly hard reboots.
When i look at dmesg i don't find anything, but there is a strange
entry:

pid 24931 (dot), uid 0: exited on signal 11 (core dumped)
pid 24932 (dot), uid 0: exited on signal 11 (core dumped)
pid 24935 (dot), uid 0: exited on signal 11 (core dumped)
pid 24936 (dot), uid 0: exited on signal 11 (core dumped)
pid 27343 (dot), uid 0: exited on signal 11 (core dumped)
pid 27344 (dot), uid 0: exited on signal 11 (core dumped)
pid 27347 (dot), uid 0: exited on signal 11 (core dumped)
pid 27348 (dot), uid 0: exited on signal 11 (core dumped)
pid 29714 (dot), uid 0: exited on signal 11 (core dumped)
pid 29715 (dot), uid 0: exited on signal 11 (core dumped)
pid 29727 (dot), uid 0: exited on signal 11 (core dumped)
pid 29728 (dot), uid 0: exited on signal 11 (core dumped)

There is also a dot.core in /root

do you now what's the problem ?
