I have a TransportClient connecting to a 2 node search cluster over NAT. The client starts up fine, over time I'm experiencing a NoNodeAvailableException though. Are there any configuration changes recommended for clients over NAT. I've already discovered to turn sniff off, since that hung the launch. I'm using 0.19.8 Thanks, Andy -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Heres the deal, I start the app and the client connects and works fine. After a certain amount of time, a search request fails and writes these logs. It writes disconnect and connect log almost immediately. The next requests fail. 2013-03-08 12:51:29,040 DEBUG (netty:94): [SearchClient] disconnected from [[#transport#-1][inet[searchserve1/39.162.203.38:9300]]] 2013-03-08 12:51:31,993 DEBUG (netty:94): [SearchClient] connected to node [[#transport#-1][inet[searchserve1/39.162.203.38:9300]]] 2013-03-08 12:51:47,994 DEBUG (netty:94): [SearchClient] disconnected from [[#transport#-2][inet[searchserve2/39.162.203.39:9300]]] 2013-03-08 12:51:52,072 DEBUG (netty:94): [SearchClient] connected to node [[#transport#-2][inet[searchserve2/39.162.203.39:9300]]] 2013-03-08 13:27:10,115 DEBUG (netty:94): [SearchClient] disconnected from [[#transport#-2][inet[searchserve2/39.162.203.39:9300]]] 2013-03-08 13:27:14,272 DEBUG (netty:94): [SearchClient] connected to node [[#transport#-2][inet[searchserve2/39.162.203.39:9300]]] 2013-03-08 13:27:20,975 DEBUG (netty:94): [SearchClient] disconnected from [[#transport#-1][inet[searchserve1/39.162.203.38:9300]]] 2013-03-08 13:27:24,303 DEBUG (netty:94): [SearchClient] connected to node [[#transport#-1][inet[searchserve1/39.162.203.38:9300]]] -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
