Apparently something goes wrong with the refresh(), or right before the
refresh (someone stole the lock, for some reason.) Can you look at the
contents of the logs/locks file at the time of the problem ? It might give
some clue as to who or what stole or broke the lock. It might also be a
clock syncronization problem; do you run mailman on more than one machine ?
(say, split mail and web machine ?) Does the machine it runs on, have a
steady clock or do you run 'ntpdate' every 10 minutes because the clock is
heavily skewed ? (This happens on some of our early Pentium-II's, can be as
much as a few minutes (!!) per hour. An hourly ntpdate fixes the symptoms,
but I imagine it can screw Mailman bigtime :P)
