Public bug reported:
Hi I'm running the 2.5K mailman list with postfix on a Ubuntu 12.04.2 LTS with about 500MB of memory. Lately I was checking munin about the health of that machine and was a little surprised to see that it's running heavily into swap. After a reboot of the machine it continously starts to use more and more memory/swap and tops after about two weeks - two weeks where no newsletter was sent out to the list.
I attached two sets of munin graphs and screenshots of the top command. In the first munin shot the first small drop is when i stopped postorios, the second big drop is when i stopped mailman. After a few hours i started mailman again and it started to eat up memory again and after about 5 days it's already using 3 quarters of the max. Did anyone see similar behavior? The machine is rather small, but shouldn't that be enough to run a list? What minimal resources would you recommend? What else can/should I check to give more insight into this issue? Peter
