Using Postfix.  I'll check the FAQ regarding name resolution

We're seeing it regularly grow to 60 or 70 MB.  Without much in
the queue.

Sorry about asking for help in the Bug system.  I'm on the lists
now and I'll do the right thing in the future.  I know better.  I
just had a long brain fart.

Apologies and thanks,

> Here is a current snapshot of the bug.
> Project: Mailman
> Category: mail delivery
> Status: Closed
> Resolution: None
> Bug Group: More Information Needed
> Priority: 5
> Summary: qrunner consuming much memory
> Details: Having performance problems.
> Running Mailman 2.0rc3 and Python 2.0 on Solaris 2.5.1.  This is an old system, a sun4u, UltraSPARC 167Mhz, 256 MB RAM.
> Mail to a Mailman list can take up to five or six hours to deliver (rarely that long, but 30 minutes is common).  Mail to local users, bypassing Mailman, finishes in the 1 to 5
> second range.
> I found that qrunner runs for about 2-7 minutes each time
> it starts.  By the time it quits, it's grown to between 65 and 90 MB in memory.  I made the cronjob run every five minutes instead of every minute, and that eliminated the "can't get qrunner lock" message in logs/error, but didn't help the performance.
> There are never many files in ~mailman/qfiles.  At present, there are two .msg and .db files.  qrunner just started about 30 seconds ago and it's already up to 47 MB.
> Is this much memeory usage normal?
> By the way, I feel like a heel asking for help on the bug tracking system.  Is there a better place for me to be posting my questions?
