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.
