I don't know if anyone has been having problems like this, but we occassionally have procmail lockup on us with the following log messages: Nov 4 11:58:53 xxxx procmail[5047]: Out of memory as I tried to allocate 134582 620 bytes Nov 4 11:58:53 xxxx sm-mta[5046]: gA4JvmiZ005045: to="|exec /usr/bin/procmail", ctladdr= (1001/100), delay=00:01:05, xdelay=00:01:0 4, mailer=prog, pri=156955, dsn=4.0.0, stat=Operating system error We happen to be using Debian "woody" with Apache 1.3.25, Sendmail 8.12.3, Procmail 3.22, and Postgresql 7.2.1
