Hey folks,
I recently installed a production server using -CURRENT as of
January 4th's snapshot. This is on an i386 machine. Dmesg at
the bottom.
This system uses Postfix and ClamAV, and I use clamav-milter to
scan all messages for viruses. Unfortunately, this installation
was necessitated by a system failure, so I didn't have a lot of
time to stress test the environment.
Now I am having issues with clamav-milter either going off into
la-la land or dying completely after a short period of time, usually
between 5-20 minutes. It doesn't always seem to die (ie, the
process dying), sometimes it just appears to not respond any longer.
Either way, Postfix starts returning a 451 (service not available)
when the milter fails.
I am running clamav-milter as follows:
>From /etc/rc.conf.local (wrapped for readability):
clamav_milter="--sendmail-cf= --headers --force-scan
--max-children=3 --timeout=60
--quarantine-dir=/var/clamav/quarantine
/var/spool/postfix/clamav/clamav-milter"
>From /etc/rc.local (wrapped for readability):
if [ X"${clamav_milter}" != X"NO" -a
-x /usr/local/sbin/clamav-milter ]; then
/usr/local/sbin/clamav-milter ${clamav_milter} && \
echo -n ' clamav-milter'
sleep 10
chmod 777 /var/spool/postfix/clamav/clamav-milter
fi
I see nothing in /var/log/clamd.log when the milter fails. I have,
however, caught a failure via ktrace:

Crap, OK, it looks like it died checking the HTML content of an
email. I disabled that in clamd.conf (ScanHTML no) and have restarted
it, and it's behaving exactly the same (still failing).
Have any of you seen any issues with the recent snapshots? I
upgraded to last night's snapshot, but the packages are in flux with
another build so I haven't been able to update all my packages yet.
Any help would be appreciated!
Benny
