Re: [Mailman-Users] Excessive cpu usage
Hi there..
I verified this.. the MTA seems to be configured correctly. Since switching to Exim recently, mailman lists have worked as they should.
As I mentioned earlier, some files are constantly being created in the out queue directory. I wasn't right when I said earlier that there was no traffic, apparently there is one message in the out queue, according to the contents of those files.
What makes me unable to diagnose the problem however is that nothing shows up in neither the mailman log files nor exim's log files.

Hello
Hi
I'm running mailman 2.1 on a linux machine. My problem is that the mailman qrunner daemon constantly consumes 65-95% of cpu time. Nothing shows up in the logs while this goes on. Any ideas of how to locate the fault?
The problem might be the message size. Mailman parses all the messages with 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,

The FAQ that is included in the Mailman download indicates that it could also be a problem with your MTA. Make certain that your MTA isn't set up to do DNS lookups on each address.

I had a similar problem after a recent MTA reconfiguration. I traced it to the fact that the my MTA was no longer listening on the port that I has specified with the SMTPPORT variable. Once I set SMTPPORT correctly, qrunner CPU utilization returned to normal and list posts were delivered.
