Milter gone wiggy? Maybe spamd?

[Dan O'Brien]

Environment is Fedora Core 1 (fully up-to-date w/ patches); SendMail 
8.12.10-1.1.1 (Fedora Core RPM); SpamAssassin 2.63; spamass-milter 
0.2.0+cvs.

Yesterday, at approximately 5:20pm, my server stopped filtering spam... it 
just decided to happily pass it along to its intended recipient.  All the 
processes appeared to be running.  /var/log/maillog shows calls to spamd, 
and it responding to connections, just doesn't seem to be doing any 
processing...  Nothing on /var/log/messages.

On closer inspection and some further thought, it's probably a problem 
with SPAMD, since the milter seems to be getting some response from 
SpamAssassin... But if anyone can offer any insight, I'd appreciate it.
