[Mailman-Users] mailmanctl stop working?

[Maickel Pandie]

Hi,

Yesterday I  tested my server Mailman + Postfix,
I start mailmanctl and postfix service,
When I sent 40 email with 15 MB attachment size from another computer,
Postfix received all email I sent but Mailman suddenly stop working, so I
have to start again mailmanctl after all email had been recieved by Postfix.
Can you tell me why this situation happen?
