It is unclear why there was more that one .bak unless you are running
multiple slices for IncomingRunner. One .bak file would be the
'backup' entry for the message currently being processed by the
IncomingRunner waiting for the lock.

It appears that something, possibly a web CGI, died and left the list
locked. The lock files themselves had a lot of information, but they
are gone. See
<http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq04.076.htp>.

At this point, there may be information in Mailman's 'error', 'locks'
and/or 'qrunner' logs that would help.

If it in fact was the case that it was one stale lock causing the
problem, it would have been sufficient to simply remove the one
<listname>.lock.<hostname>.<pid>.<seq> file whose <pid> was gone and
whose name was the contents of the <listname>.lock file, and then also
remove the <listname>.lock file itself.

Note also, that by deleting the .bak files, you probably lost the
messages they contained. Had you left them, they would have been
'recovered' when you restarted Mailman.
