3.1.2 spamd dies without warning

[up...@3.am]

I upgraded from 3.0.4 yesterday without too much trouble...once I got
3.1.2 online, I noticed a nice reduction in false negatives, and cpu
remained low (holiday here in US).

This morning, spamd died with no warning, except of course a huge increase
in spam.  Nothing in /var/log/messages, and only this in maillog:

It took me about an hour and a half to notice it.  I restarted spamd and
it's going ok at moderate cpu use.  Here are my flags with which I start
spamd:

/usr/local/bin/spamd -m 15 -d -x -r /var/run/spamd.pid

The only changes I made with the upgrade were that I enabled SPF, DCC and
Pyzor.  When building the new version, it did complain about an outdated
razor2 software, but as it was only a warning (and I'd never had problems
with it before), I didn't bother to UG.

Any ideas as to the possible cause?
