>From a kernel which was cvsup'd last night. This appears to happen
when under load. I won't discount bad memory on my machine, but it's
hard to tell...
Also, FWIW, the new VM patches from last night: I still end up getting
the occaisional spurious sig 11's on sendmail and cron. Restarting the
daemons appears to make them go away -- which diminishes my suspicions
of memory hardware problems. No panics in VM code, though, which is a
good thing.
