Am having a Netty related issues in my storm cluster where the spout stops consuming after a while. The corresponding worker logs show - *2015-09-12T23:28:23.391-0400 b.s.m.n.Client [ERROR] connection attempt 26 to Netty-Client-trsttel2pascapp01.vm.itg.corp.us.shldcorp.com/10.2.70.18:6707 <http://Netty-Client-trsttel2pascapp01.vm.itg.corp.us.shldcorp.com/10.2.70.18:6707> failed: java.lang.RuntimeException: Returned channel was actually not established* *2015-09-12T23:28:23.391-0400 b.s.m.n.Client [INFO] connection attempt 27 to Netty-Client-serverstorm1.myorg.com/10.2.70.18:6707 <http://Netty-Client-serverstorm1.myorg.com/10.2.70.18:6707> scheduled to run in 392 ms* *2015-09-12T23:28:23.784-0400 b.s.m.n.Client [ERROR] connection attempt 27 to Netty-Client-**serverstorm1.myorg.com <http://serverstorm1.myorg.com>**/10.2.70.18:6707 <http://10.2.70.18:6707> failed: java.lang.RuntimeException: Returned channel was actually not established*
The corresponding supervisor logs had *2015-09-12T23:28:23.018-0400 b.s.d.supervisor [INFO] 32e3f906-3869-4f0c-ac1c-4916615daf99 still hasn't started* *2015-09-12T23:28:23.518-0400 b.s.d.supervisor [INFO] 32e3f906-3869-4f0c-ac1c-4916615daf99 still hasn't started* *2015-09-12T23:28:24.019-0400 b.s.d.supervisor [INFO] 32e3f906-3869-4f0c-ac1c-4916615daf99 still hasn't started* I had storm version 0.9.3 when this issue occurred and had upgraded to 0.9.4 and 0.9.5 to seek relief, but the issue still persists. Am not sure what else to do. Am not even sure why this issue occurs and what triggers it. Any help would be great and appreciated. Thanks Kashyap
