Signal 6 after powerfail

Hi all,

I've recently been seeing this happen on my FreeBSD system and was
wondering whether anyone else has any experience with this sort of thing:

from /var/log/messages:
> Nov 20 11:32:30 cache /kernel: NMI: power fail
> Nov 20 11:32:30 cache /kernel: pid 143 (squid), uid 65534: exited on signal 6

The system remains running OK but squid exits. It is the only process
that behaves this way when the NMI is issued.

TIA.

Ben

              So I installed FreeBSD.
