RequestCorrelator "channel is not connected" error during shutdown ------------------------------------------------------------------ Key: JGRP-1958 URL: https://issues.jboss.org/browse/JGRP-1958 Project: JGroups Issue Type: Bug Affects Versions: 3.2.12 Reporter: Dennis Reed Assignee: Bela Ban Priority: Minor Fix For: 3.6.5 Error logged during shutdown of a channel due to RequestCorrelator failing to send a reply: ERROR [org.jgroups.protocols.UNICAST2] (OOB-17,shared=tcp) couldn't deliver OOB message [dst: server1/web, src: server2/web (4 headers), size=62 bytes, flags=OOB|DONT_BUNDLE|RSVP]: java.lang.IllegalStateException: channel is not connected at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.down(MessageDispatcher.java:617) [jgroups-3.2.12.Final-redhat-1.jar:3.2.12.Final-redhat-1] at org.jgroups.blocks.RequestCorrelator.handleRequest(RequestCorrelator.java:544) [jgroups-3.2.12.Final-redhat-1.jar:3.2.12.Final-redhat-1] at org.jgroups.blocks.RequestCorrelator.receiveMessage(RequestCorrelator.java:391) [jgroups-3.2.12.Final-redhat-1.jar:3.2.12.Final-redhat-1] at org.jgroups.blocks.RequestCorrelator.receive(RequestCorrelator.java:249) [jgroups-3.2.12.Final-redhat-1.jar:3.2.12.Final-redhat-1] at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.up(MessageDispatcher.java:600) [jgroups-3.2.12.Final-redhat-1.jar:3.2.12.Final-redhat-1] [incoming JGroups message] It appears to just be a timing issue between shutdown of the channel and RequestCorrelator processing the message, which triggers a response message. It would be good to either avoid triggering the exception in the first place, or suppress the error log during shutdown.
