That sounds _exactly_ like what I've been seeing and reporting with netbsd-4 for over six months now.

The system _seemed_ more stable for a while after switching over to the wrstuden-fixsa branch of netbsd-4.

However I think my understanding of the symptoms and their frequency of occurrence is still not right.

The system survived for a maximum of something like 47 days, but then crashed every day for a week.

I cannot seem to correlate the problems with any regular activity other than the nightly cron jobs -- however they seem to just be victims of the problem too, not the cause.

See kern/37993 and kern/38019.  Probably those two PRs should be merged.
