[Mailman-Users] Mailman Crashes Regularly

[Aaron Kreider]

  I'm getting regular mailman crashes every 2-4 weeks.  I've had 4 so 
far.  I'm running a centos VPS with mailman 2.1.13.

What is the best way to restart mailman?  I've been restarting the 
entire vps, which obviously is a bad idea.  What can I do to prevent 
this from happening?

Here is the error log entries from when it crashed:
