[Mailman-Users] Excessive memory usage?

[David Pieper]

My mailman seems to use a LOT of memory.

RH 7.3
Python 2.2.2
Mailman 2.1.2

I have 3 lists so far, 2 have < 3 users, and the other has 79052 users.
(It's an announcement only list)

Here's the ps listing:

mailman  25064  0.0  0.1  6244  580 ?        S    11:39   0:00 /usr/bin/python /var/mailman/bin/mailmanctl -s -q start
mailman  25065  0.0  0.4  6300 1712 ?        S    11:39   0:00 qrunner /var/mailman/bin/qrunner --runner=ArchRunner:0:1 -s
mailman  25066  2.5 14.6 67144 56404 ?       S    11:39   0:51 qrunner /var/mailman/bin/qrunner --runner=BounceRunner:0:1 -s
mailman  25067  8.8 13.9 75660 53516 ?       S    11:39   3:01 qrunner /var/mailman/bin/qrunner --runner=CommandRunner:0:1 -s
mailman  25069  0.0  0.4  6292 1720 ?        S    11:39   0:00 qrunner /var/mailman/bin/qrunner --runner=IncomingRunner:0:1 -s
mailman  25070  0.0  0.4  6332 1756 ?        S    11:39   0:00 qrunner /var/mailman/bin/qrunner --runner=NewsRunner:0:1 -s
mailman  25071 16.5 17.0 70408 65776 ?       S    11:39   5:39 qrunner /var/mailman/bin/qrunner --runner=OutgoingRunner:0:1 -s
mailman  25073 24.1 17.4 73364 67268 ?       S    11:39   8:14 qrunner /var/mailman/bin/qrunner --runner=VirginRunner:0:1 -s

Here's the output from free when mailman is running:

[root at ns1 mailman]# free
              total       used       free     shared    buffers     cached
Mem:        384900     374252      10648          0      20448      32692
-/+ buffers/cache:     321112      63788
Swap:       787424     318628     468796


And when it's not:

[root at ns1 mailman]# free
              total       used       free     shared    buffers     cached
Mem:        384900     108904     275996          0      21180      28712
-/+ buffers/cache:      59012     325888
Swap:       787424      61468     725956


Is this normal?

Enjoy,
