[Mailman-Users] Problem with long term mailman setup.

[Paul Rubin]

Hello,
 
Yesterday at 9:40 in the morning mail just stopped flowing.  Messages came
were stored in the archive and never sent out.  I tried restarting
everything and looking for locks, etc.  There were no messages in the log to
indicate anything out of the ordinary.  
 
The only thing I could find strange was the the qfiles/out directory had
hundreds of file in it.
 
Finally with no other ideas I Upgraded from Mailman 2.1.6 to Mailman 2.1.8
and mail started flowing.  When 2.1.8 was started there were a large number
of errors:
 
Jul 12 17:46:08 2006 (22768) SHUNTING:
1152740247.566874+dc88e771186bc6266faeda03363eb2b3a3076cd2
Jul 12 17:46:08 2006 (22768) Uncaught runner exception: 'str' object has no
attribute 'get_sender'
Jul 12 17:46:08 2006 (22768) Traceback (most recent call last):
  File "/var/mailman/Mailman/Queue/Runner.py", line 111, in _oneloop
    self._onefile(msg, msgdata)
  File "/var/mailman/Mailman/Queue/Runner.py", line 159, in _onefile
    sender = msg.get_sender()
AttributeError: 'str' object has no attribute 'get_sender'

After that some mail went out and some was lost.
 
Now this morning, after sending half a dozen messages, it appears to be
happening again.  The seventh message showed up in the archive and has not
apparently gone anywhere else.
 
Is there any information from the mailman daily status report that might
provide any clue to what is happening?
 
Thanks.
Paul.
