We've been having some trouble with 0.67 crashing. I believe it has to
do with a mail loop created between hotmail and a forwarded local user
account.
Right before the crash all memory will be used. Before we started using
ulimits we would get:
Mar 4 14:34:33 minos kernel: Out of Memory: Killed process 21902
(clamd).
We have 1Gb RAM and another Gb of swap so it is pretty hungry.
Every file in the directory listed has the exact same message (there are
16 of them):
Final-Recipient: rfc822;<deleted>@hotmail.com
Action: failed
Status: 5.2.3
Diagnostic-Code: smtp;552 5.2.3 This message is larger than the current
system limit or the recipient's mailbox is full. Create a shorter
message body or remove attachments and try sending it again.
I'm running the crashhat rpms (recompiled locally) with clamav-milter
and ulimits on the clamav user to prevent it from eating all the RAM
(this happens a lot, I believe related to this crash).
clamav-milter --version:
ClamAV version 0.67, clamav-milter version 0.66n

For those interested in ulimits: We had to make a small modification to
the init script to make it use ulimits.
change:

to:
daemon --user clamav /usr/sbin/clamd
