[Mailman-Users] Mailman stuck : mailmanctl dead with messages in /qfiles/in

[Jérôme]

Hi.

Mailman somtimes gets stuck on my installation. By stuck, I mean I get no
mail and no subscription notification. Until I relaunch it.

I generally does not happen for a few months, but it is the second time this
month.

Debug info
----------

Last time it got stuck, I did the modification suggested here :

http://wiki.list.org/display/DOC/4.73+How+do+I+debug+smtp-failure+problems+-+delivery+to+user-example.com+failed+with+code+-1-+and+Low+level+smtp+error-

modified 
/var/lib/mailman/Mailman/Handlers/SMTPDirect.py
to add
self.__conn.set_debuglevel(1)

Configuration
-------------

Not sure this is useful, but 
/etc/mailman/mm_cfg.py contains
MTA='LocalPostfix'
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['domain1.tld', 'domain2.tld']

I would like to figure out what is happening, therefore I don't relaunch, in
case there would be some more information I could get.

Any advice ?

Thanks.
