Hello.. and thanks for the response.

I probably should have mentioned that there is currently no traffic on
the server.. no messages are being sent and all queues are empty.

The problem might be the message size. Mailman parses all the messages
python,who is a little unefficient.

For example, on my mailman machine, messages of size=300 KB required
300 MB of 
RAM for processing... and used up (+90%) the CPU (P-III-Xeon-550).

In my case, the solution was to reduce the message size,
