[Mailman-Users] archRunner hogging CPU

[Anne Ramey]

This is a dedicated server that does mailman and one low traffic web 
site.  CPU load is usually ~0.05 or there abouts.  I have never seen the 
archive runner taking up so much CPU.  It's been doing it for hours.  
The other queues are running fine.  Posted messages go out in a timely 
manner.  It's just taking 15+ minutes to archive the messages.  It's 
hogging the CPU and making other things  I'm trying to do slower to 
respond, especially web site functions (including mailman's admin sites).
