[Mailman-Users] Mailman getting stuck while trying to send a message

[Remi Delon]

Hello,

For several weeks my mailman instance sometimes just stops delivering 
messages. Restarting Mailman seems to fix it and messages that were in 
the queue do get sent eventually.

Today I got a hint as to what might be happening ...
As Mailman seemed to be stuck again, I ran "mailmanctl stop" and watched 
all the log files.
When I ran "mailmanctl stop", the following line suddenly appeared in 
the "smtp" log file:

Apr 24 07:39:11 2005 (26501) 
<BAY104-F2054D7459D5E9CBDBFD56ACC2D0 at phx.gbl> smtp for 155 recips, 
completed in 159722.267 seconds

Wow ! So it seems that Mailman was stuck (for more than 40 hours) while 
trying to send this message and that stopping it made it stop trying to 
send this message and move on to the next ones (after I restarted it).

I also saw a lot of these appear in smtp-failure:

smtp-failure:Apr 24 07:39:11 2005 (26501) delivery to 
<removed-email-address> failed with code -1: please run connect() first


Does anyone have any idea as to why Mailman gets stuck trying to send a 
message sometimes ? If a resource (DNS, remote mail server, ...) is 
unavailable, shouldn't it timeout after a while ?

I'm currently running version 2.1.4. Could this be fixed by upgrading to 
the latest version ?

Thanks,

Remi.
