[Mailman-Users] archRunner hogging CPU

[Anne Ramey]

It appears my archive runner is flipping out today.  It is hogging the 
CPU and can't seem to keep up with the messages.  I restarted mailman 
and it doesn't seem to have helped.  It doesn't appear as if we are 
seeing any unusual traffic, so I can't think of what would cause this.  
It isn't completely stuck...it's processing messages, just really slowly 
and taking lots of CPU to do it.  We are using Exim version 4.43 on RHEL 
4 and mailman version 2.1.9rc1.  Ideas?
