On a 4.8-RELEASE-p17 machine running Sendmail 8.12.8p2 we are seeing the
following errors in /var/log/{messages,maillog}:
sm-mta[50018]: i3TDTBcR050018: SYSERR(root): out of memory: Cannot
allocate memory
I will include more info as we can gather it.

Do you have excessive numbers of sendmail processes running, perhaps due to someone mail-bombing your server? There have been security holes fixed in sendmail since 8.12.8, and 8.12.11 is the most current version. Some of the fixes have been backported to FreeBSD 4.8, (that's what the p2 means), but I'm not sure whether your version is completely up-to-date. -- -Chuck

The symptoms began when clamd exited with a signal 6. Thanks for the suggestions. -Nick

There are was such trouble with clamav-milter from clamav-devel before Apr 2004 on FreeBSD 4.9 (sendmail 8.12.9p2) I had that problem with 1.5 minutes or more while transferring single message to sendmail with clamav-milter. Sendmail has no trouble without clamav-milter or with other one (For example - spamass-milter-0.2.0_1 port) Clamav was fixed for that bug, but real problem could be (on not to be) inside sendmail. P.S. I am not sure that my message will be posted to freebsd-security@, but you can forward it to upcoming discussion if it's interesting. -- Regards Eustrop
