Hi All :)
I'm using Slony1-1.2.9 and PostgreSQL8.0.11, and i have a problem with 
sl_event,
when i setup the replication (with the slon_tools) everything be OK,
but after then, the engineer of the our partner setup firerwall, and we 
have connection only from slave to master, and no connection from master 
to slave....
at first look with the replication data it's OK, but after the 
reconfigure firewall (when we have connection both side from slave to 
master and from master to slave)
and restart slon daemon, i have such messages in LOGS on SLAVE

I'm manually deleting 5-6 rows from sl_event on slave and data 
replication OK,
BUT I HAVE ~300K rows in sl_event on master, and that not cleaning....
i see this on master logs

I'm right that cleanupThread call PL/SQL function cleanupevent() ???
I'm not understant why the number of rows in sl_event more and more, and 
they not cleanup......

in view sl_status i see the huge lags....
