Intermittently, but increasingly frequently, the mailman I'm running
is getting into a state where messages are received and archived, but
not logged in the "posts" file or sent out by smtp.
This situation usually resolves itself after I kick it enough. Maybe
it would resolve itself if I didn't kick it at all. I would like to
understand what's happening, so I can either stop it happening, or
kick it more efficiently.
This is on a mailman 2.1.10 installed from source on ubuntu 7.10. The
machine is running postfix. The mail log indicates that postfix has
passed the stuck mails to mailman:
Jun 6 12:12:47 serpent postfix/local[12334]: 8139F240324:
to=<[EMAIL PROTECTED]>, relay=local, delay=0.31,
delays=0.05/0.01/0/0.25, dsn=2.0.0, status=sent (delivered to command:
/home/mailman/mail/mailman post bonnienews)
I've checked all the things in
<http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq04.078.htp>.
At one point, there was a second (old) OutgoingRunner process after I
had stopped and started mailmanctl several times, which I had to kill
by hand, but usually this isn't the case.
Here's my kick_mailman.sh script; I also reboot the system when I've
tried this and it hasn't worked. When the queue gets unclogged, it
isn't ever immediately after any of these things, including the
reboot.
There are errors in the error log:
Jun 05 13:38:41 2008 (7364) Failed to unlink/preserve backup file:
/home/mailman/qfiles/out/1212668722.1033101+99ec79fd321b54afb77e0ef5c8b0f5d2625e6aea.bak

and in the smtp-failure log:
Jun 06 13:11:29 2008 (16109) Low level smtp error: (4, 'Interrupted system
call'), msgid: <[EMAIL PROTECTED]>
Jun 06 13:56:33 2008 (5154) SMTP session failure: 250, ok, msgid: <[EMAIL
PROTECTED]>
Jun 06 13:56:33 2008 (5154) delivery to <redacted>@gmail.com failed with code
-1: (4, 'Interrupted system call')
What is happening between when mailman gets my mail and when it
finally agrees to disgorge it via smtp? It is in the stuck state
right at the moment, if someone can walk me through more debugging.
