[Mailman-Users] How to trace a lockup?

I'm experiencing a lockup condition on FreeBSD-3.4 with mailman.  It's 
taking an inordinate amount of time (almost indefinately) stuck in the 
poll state.

The qrunner process seems to stick in the "poll" state (as reported by 
top) indefinately.  lsof shows a socket open to the mailer (postfix or 
sendmail both tried in this case) and it also shows 0 bytes in the
transmit and recieve counts.

How do I debug this?  Has anyone looked into locked up qrunner

I've tried to switch to calling sendmail from the command line, but
this piece of code seems broken.
