Are the last two lines your perceived problem? Is the NOTIFY working? There's really not enough information here to actually understand what you're asking. Based on the log information, it looks like a client program issues a notify, then drops the connection. Could be because in intervening network control device times out the TCP state, or could be because the client drops the conneciton, or because the client crashed, or is poorly implementd in that it looses its TCP socket. In any event, the 4 hour lag between the NOTIFY and the conneciton drop during which nothing happens seems to indicate that the two events are probably not related. Is any of that helpful? I feel like I don't understand your question and suspect that you didn't receive an answer to your first post because most people didn't understand it. If my comments don't address your question, perhaps try describing it differently. -- Bill Moran <wmoran@xxxxxxxxxxxxxxxxx> -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
