OK, From what you report here and elsewhere, it appears the issue was
with OutgoingRunner not processing Mailman's 'out' queue. If the above
log excerpt (appears to be from a mailmanctl restart) is complete, you
will note that there are three entries for most runners, e,g.

Stopping.

[restarting]

But there is only one for OutgoingRunner

Stopping.

suggesting that it was hung and never terminated.

Had it been me at that point, I would have stopped Mailman and made sure
it was completely stopped per the FAQ at <http://wiki.list.org/x/_4A9>,
and then started it to see if that fixed the problem. If the out queue
were still not being processed, I would try to trace the OutgoingRunner
process to see where it was hung.
