Hi,
My system: Solaris 2.7, sendmail 8.11.2, cyrus 2.0.12, sasl 1.5.24, openssl
0.9.6
berkeley-db 3.1.17, perl 5.6.0
I've experienced following Problem an right now tracking it down. Maybe
someone can share some ideas....
At some point in time email doesn't get delivered any more. Mailqueue gets
longer and longer with "in transit mails having a '*'" These mails seem to
stay in the queue forever. Maybe there is also a sendmail problem not timing
out. Logfile of sendmail says: "timeout waiting for input from local during
Draining Input". The mails are destined to be delivered locally to the
cyrus-Mailsystem. I see deliver-Processes and lmtpd's obviously for each
sendmail-process trying to deliver mail.
If I kill the cyrus-master-process and restart it everything seems to work
again. After running the mailqueue every mail gets delivered at once.
The whole mess seems to start when a user via dial in drops connection.
Several old imapd's of this user are hanging around (he don't owns them, but I
checked with the logfile for who logged in)
So I blame a deadlock between imapd doing something and lmtpd trying to get a
ressource-lock or somthing like that before delivering mail.
Can someone please give a hint how to get more info whats going on with
debugging swiches or something? I didn't find any hints in the manpages about
how to turn really verbose debugging on.
Thanks for any hints,
Anton
