I am doing something wrong. I am running mailman with about 100 lists (announce only). A couple are pretty big (40K + addresses). They, however, are used infrequently. The big list has one weekly mailing and the others much less often. Currently, there is NO mail queued or being sent (tail -f on maillog is silent), yet doing a top on the mailman process shows mailman consuming 1240M of virtual memory and a task size (RES) of 811M.
I am no Linux Performance Tuning expert, but the system seems pretty pokey. This is with no mail going out (and the occasional subscribe / unsubscribe trickling in).
When a mailing goes out, the system becomes virtually unresponsive, usually resulting in a http 500 error. If ssh in to the system, I am eventually able to kill mailman, at which time the system perks right up again. System is a P4 with 1 GB of RAM.
Mailman 2.19rc1
What am I missing?
Thanks,
pete
