lock busy! Is another session active?

All,

I could use a little help here.  I'm using fetchmail to get my mail through
APOP, and getting the following error message:

  fetchmail: flock: '/usr/spool/poptemp/.srhea.pop': No locks available (46)
  fetchmail: lock busy!  Is another session active?
  fetchmail: Lock-busy error on srhea(_at_)realname(_dot_)server(_dot_)com
  fetchmail: lock busy on server error while fetching from my.pop.server.com
  fetchmail: Query status=9 (LOCKBUSY)

In more detail:

  fetchmail: 5.5.0 querying my.pop.server.com (protocol APOP) at Sun, 25 Feb

Any hints on how to debug this would be greatly appreciated.  There is no
other version of fetchmail running.  It seems like all I need is a way to
clear the lock, but I'm not sure.

Please send responses to srhea(_at_)gibbon(_dot_)cs(_dot_)berkeley(_dot_)edu, 
since because of
this error I can only send mail from my srhea(_at_)cs(_dot_)berkeley(_dot_)edu 
account.

Thanks again,
Sean
