[Mailman-Users] Need queue error help

[John Lewis]

Greetings,

What does this error mean?  And how do I go about resolving it?

Traceback (innermost last):
  File "/home/mailman/cron/run_queue", line 31, in ?
    OutgoingQueue.processQueue()
  File "/home/mailman/Mailman/OutgoingQueue.py", line 121, in processQueue
    recip,sender,text = marshal.load(f)
EOFError: EOF read where object expected

I get one of these messages every half hour.

Thanks
