I asked this before, but I don't know if I specified the specifics of 
the issue.  I just received the following messages:

NOTICE:  Slony-I: cleanup stale sl_nodelock entry for pid=2632
CONTEXT:  PL/pgSQL function "cleanupevent" line 77 at perform
NOTICE:  Slony-I: cleanup stale sl_nodelock entry for pid=9725
CONTEXT:  PL/pgSQL function "cleanupevent" line 77 at perform

This was from the database I just started replicating.  I don't 
understand why there would be a 'stale' anything when first starting 
replication.  The message appears about the time the the initial 
replication is complete.

So, this is not something I should be concerned with?
