Yedidia,
Are you by chance using Bill Stearn's sa-blacklist?
Same thing happened on my mail server yesterday - it almost ground to a halt, stalled procmail processes all over the place, sendmail errors identical to yours - very ugly.
Eventually traced it down to the fact that the sa-blacklist.current had inadvertently quintupled (5x) in size overnight, from 1.5 to almost 7 MB in size. I use daily auto-updates of this list so hadn't noticed until the side-effects appeared.
See the thread titled 'blacklist brings system to halt' in this list for further details.
Regards, Damon
I'm in the process of setting a new mail server on a Dual Xeon HT machine w/
RH Enterprise AS3, sendmail 8.12.11 and SPAMASSASSIN 2.63 that run via procmail using spamd/spamc way.
I found this on my logs (/var/log/maillog)Jun 29 16:54:49 mail-server sendmail[5512]: i5TC88xl005078: timeout waiting for input from local during Draining Input
Jun 29 17:02:49 mail-server sendmail[5512]: i5TC88xl005078: to=, delay=01:54:39, xdelay=00:10:00, mailer=local, pr
i=213649, dsn=4.0.0, stat=Deferred: local mailer (/usr/bin/procmail) exited with EX_TEMPFAIL
and there was also a stucked spamd process from this user..
sounds like spamc was stucked then sendmail get in time out for waiting to procmail...
any way to know why spamc/spamd was stucked / what could cause this problem ?
thanks,
--Yedidia
