Here's the pertinent details for the system concerned:
# ps aux | awk '{print $1 "\t" $3 "\t" $4 "\t" $10 "\t" $11}'
USER %CPU %MEM TIME COMMAND
nobody 78.1 14.7 0:11.69 /usr/bin/spamd
root 0.0 0.0 0:28.50 (pagedaemon)
root 0.0 0.0 0:05.64 (vmdaemon)

root 0.0 0.0 0:25.62 /sbin/init
(non-relevant processes snipped - sshd/csh/sh etc).
Notice the spamd load? This looks a little high to me. But our spam
rules are huge (the normal rules that come with Spamassassin + 1168
custom rules). Those custom rules round out to 3504 lines of
RULE/DESCRIPTION/SCORE..... so relatively large. FWIW we're running
spamassassin 2.55.
I can send anything that might shed more light on the problem
(sendmail.cf exerpts etc)....just let me know :-)
Cheers,
James
