Does slon just stop writing to the file? As you can see in the normal log file, the localListener thread sees the STORE NODE event and then the STORE PATH event a bit further down. 2010-10-29 15:01:38 UTCDEBUG2 localListenThread: Received event 1,5000000179 STORE_NODE 2010-10-29 15:01:38 UTCCONFIG storeNode: no_id=2 no_comment='slave' Once it processes that store node event it then starts the remoteWorker and remoteListener threads that actually do stuff In the error case, if you query the sl_event table on the master you should see the STORE NODE and STORE PATH events. (this is worth confirming). The question is why is the slon not getting to this events. What event numbers are assigned to them? In the error case it got as far as 1,5000000081 in the normal case the STORE NODE event was 1,5000000180 so if the time from when you started slon until when you ran the storeNode is similar in both cases then you still have a fair number of events left to process (though processing 100 SYNC events when no tables are replicated should be pretty fast)
