We have seen such a problem report recently several times in the
mailing list (please search the archives (via Google)).

   It means that something accesses a ZODB connection which
   is no longer valid (open).
   
   As connections are closed when the request ends, this can happen e.g.
   when a persistent object was passed to a separate thread or put
   into a module's global namespace.

   The mentions posts may indicate that there is an additional
   potential cause for the behaviour.


I do not know ZExternalNews and cannot give you specific advice.
But, it may spawn a thread.
