mailman fails to deliver messages due to error

[J York]

I'm having a problem with Mailman not delivering the vast majority of
the messages that get sent to it.  It receives the messages and stores
them safely in qfiles.  Then qrunner attempts to deliver those
messages, then dies after a few are sent.

>From the log files:

$ cat qrunner
Mar 22 08:46:03 2002 (11484) Could not acquire qrunner lock

$ cat error

$ 

Qrunner is set to startup every minute.  But I can watch the error log
file and process list and watch qrunner die shortly after the above
error.  Like clockwork.

When I check to see if the above file is there, it is not.

Any ideas?

My specs:
Solaris 2.8
Python 2.1.1 (compiled w/ gcc 3.0.1)
Mailman 2.0.8
