[Mailman-Users] Mailman Sending Out Duplicates!

[Jonathan Chum]

I'm not sure what exactly is the problem, however Mailman is sending
duplicates up to 12x for a client of ours. I reviewed the dmesg.today log
file and notice it ran out SWAP space. The machine is a PIII 850 with 128 MB
RAM and 512 of SWAP space.

There are two lists that are blasted out. . . one list that's 72,500
subscribers and another list of 37,300 subscribers.

The problem usually occurs when the 72,500 subscribers are blasted out. We
did not have this problem when the client started with 50K subscribers and
the previous administrator tweaked Sendmail and Mailman.

I would think Mailman working as a robust list server should have mechanisms
to prevent duplicate emails. Reviewing the ps -auxww when the SWAP space ran
out, it looked like a few Mailman processes was sucking up all the memory.

Any ideas to fix tihs issue? Is memory the problem? I was thinking of
slapping in more memory into the machine.
