[Mailman-Developers] Log file rollovers

[Richard Barrett]

logrotate has a problem with MM 2.1.x because the qrunners operate a 
daemons and as a consequence do not close the files they are logging 
to. This leads to the problem you are observing. This is not a problem 
with MM alone. Anything that runs as a damon typically has to be HUP'ed 
after the rotation to prevent the problem.

Try extending the command logrotate uses to stop mailmanctl before the 
rotate and start it again after the rotate has been done or restart 
mailmanctl immediately after the rotation..
