This has happened with increasing intensity here, only since running mailman 2.1.1 (since March 4 or so). Note that the following is an informal bug report of what I think at least two different problems.

AttributeError: 'None' object has no attribute 'has_key' Traceback (most recent call last): File "/usr/local/app/mailman-sfs/2.1.1/bin/qrunner", line 270, in ? main() File "/usr/local/app/mailman-sfs/2.1.1/bin/qrunner", line 230, in main qrunner.run() File "/usr/local/app/mailman-sfs/2.1.1/Mailman/Queue/Runner.py", line 59, in run filecnt = self._oneloop() File "/usr/local/app/mailman-sfs/2.1.1/Mailman/Queue/Runner.py", line 88, in _oneloop msg, msgdata = self._switchboard.dequeue(filebase) File "/usr/local/app/mailman-sfs/2.1.1/Mailman/Queue/Switchboard.py", line 151, in dequeue if data.has_key('rejection-notice'):

Qrunner dies and is restarted -- but only 10 times when it really dies with

------ logs/qrunner ------------------------------------- Apr 14 11:06:24 2003 (1230) Qrunner OutgoingRunner reached maximum restart limit of 10, not restarting.

I have just now set this (MAX_RESTARTS in bin/mailmanctl) to 10000 instead of 10 (BTW, shouldn't this be configurable via mm_cfg.py as well?)

From then on, qfiles/out/* starts growing and growing and mailing list delivery becomes very slow at least in the case, where I have two (or 4) slices Outgoing Runners.

--- Bug # 2 ---

BTW: When I do have more than one runner, things get faster, *BUT* I sometimes get the same message delivered by more than one of the outgoing runners. This seems to happen (almost?) ony in the case where the queue is almost empty. But it is quite embarrassing to this twice delivered to everyone on the list.

Thank you for mailman, and thanks for feedback / suggestions / fixes ...
