[Mimedefang] filter timing out

[alan premselaar]

I'm sure this has been covered before, but i couldn't find it in the
archives (could just be i'm tired) ...

anyways, lately i've been seeing A LOT of 4.7.1 failures in my log file.
I've got my MIMEDefang spool dir on a tmpfs, and i haven't made any changes
to my filter recently.

later
Jan 20 17:43:52 uchuu mimedefang-multiplexor: Reap: Killed slave 5 (pid
16240) exited due to SIGTERM/SIGKILL as expected.
Jan 20 17:43:52 uchuu mimedefang-multiplexor: Slave 5 resource usage:
req=15, scans=5, user=88.460, sys=0.680, nswap=0, majflt=760, minflt=13997,
maxrss=0, bi=0, bo=0

the machine isn't a powerhorse, but it should still be enough to handle mail
for this domain.. (i don't receive a lot of mail, and i have maybe 12 users)

it'S a PII 400Mhz with 384MB of RAM running Redhat 7.3

it doesn't appear to be running out of slaves.  Any known issues with
spamassassin and/or network tests that I might be missing?  (i stopped
subscribing to the SA talk list because there was just too much traffic
daily and I couldn't get thru it all)

anyways, as always, any help is appreciated.
