Hi,

I just noticed a problem with our 2.1.9 installation. One of my colleagues complained that mails didn't go through to one of his lists. When I checked the logs, I found that sendmail handed the messages off to Mailman (some info redacted):

2008-04-23T15:14:23+02:00 lvr13.rrz.uni-koeln.de sendmail[21253]: m3NDEM3A021253: from=<yyy@uni-koeln.de>, size=5059, class=0, nrcpts=1, msgid=<1208956450.988675.155922491.2908.2@otrs.rrz.uni-koeln.de>, proto=ESMTP, daemon=Daemon0, relay=cherub.rrz.uni-koeln.de [134.95.19.133] 2008-04-23T15:14:23+02:00 lvr13.rrz.uni-koeln.de sendmail[21271]: m3NDEM3A021253: to="|/usr/lib/mailman/mail/mailman post xxx", ctladdr=<xxx@uni-koeln.de> (8/0), delay=00:00:00, xdelay=00:00:00, mailer=prog, pri=35271, dsn=2.0.0, stat=Sent

But there was no trace in any of Mailman's logs. On a hunch I checked the spool directory and noticed that there are 1,390 files in the "in" directory, starting at 2 pm today. I also found the message in question based on its time stamp. Some mail still goes through Mailman, but some apparently doesn't. All runners seem to be running, so I'm at a loss to explain this behavior.

Any ideas?

Update: I just noticed that the number of messages in "in" is decreasing. Could it be that something just overwhelmed Mailman so that now there is a backlog that's slowly being worked through? I don't think we ever had such issues prior to today.

Cheers, Sebastian
