IncomingRunner reached maximum restart limit of 10

I just upgraded to 2.1 from 2.0.13, and I'm getting these
errors when trying to startup the qrunner from the
startup script (this is from the $MAILMAN/logs/qrunner
log file):

On the console, I'm getting these errors which might be
more useful (just pasting 1 here, the other 9 are exactly
the same)

Traceback (most recent call last):
  File "/usr/local/mailman/bin/qrunner", line 270, in ?
    main()
  File "/usr/local/mailman/bin/qrunner", line 230, in main
    qrunner.run()
  File "/usr/local/mailman/Mailman/Queue/Runner.py", line

    filecnt = self._oneloop()
  File "/usr/local/mailman/Mailman/Queue/Runner.py", line
93, in _oneloop
    msg, msgdata = self._switchboard.dequeue(filebase)

File "/usr/local/mailman/Mailman/Queue/Switchboard.py",
line 158, in dequeue
    data = self._ext_read(dbfile)

File "/usr/local/mailman/Mailman/Queue/Switchboard.py",
line 264, in _ext_read
    dict = marshal.load(fp)
EOFError: EOF read where object expected

I'm running this on FreeBSD 4.9-STABLE, mailman version
2.1.3, python 2.3.2 (both out of the ports tree).

Any help you can send my way is much appreciated.
