As Doug suggested, it's probably an hardware fault.



However, I've many times seen boxes crash every day or two when an 
UFS+SU filesystem gets corrupted. Background fsck won't detect this.

In order to stop the crashes, I always had to boot into single user mode 
and do a fsck -y (twice if asked) on every UFS+SU filesystem.

Furthermore, if you are using SU+J, you'll have to run fsck first to 
deal with the journal and then fsck it again (ignoring the journal).

This has brought several boxes I manage back on track on many occasions.

You might want to try this, since the only downside is downtime.



HTH.
