In the unlucky case, the task to > associate the connection with the virtualhost gets executed after the virtual > host's network connection scheduler is shutdown. This leads to a NPE. The > Broker detects the NPE and shuts itself down. > {noformat} > 2016-03-18 06:41:06,748 ERROR [IO-/172.24.102.24:51029] (o.a.q.s.Main) - > Uncaught exception, shutting down. > java.lang.NullPointerException: null > at > org.apache.qpid.server.transport.NetworkConnectionScheduler.processConnection(NetworkConnectionScheduler.java:142) > ~[qpid-broker-core-6.0.1.jar:6.0.1] > at > org.apache.qpid.server.transport.SelectorThread$ConnectionProcessor.processConnection(SelectorThread.java:505) > ~[qpid-broker-core-6.0.1.jar:6.0.1] > at > org.apache.qpid.server.transport.SelectorThread$SelectionTask.performSelect(SelectorThread.java:338) > ~[qpid-broker-core-6.0.1.jar:6.0.1] > at > org.apache.qpid.server.transport.SelectorThread$SelectionTask.run(SelectorThread.java:87) > ~[qpid-broker-core-6.0.1.jar:6.0.1] > at > org.apache.qpid.server.transport.SelectorThread.run(SelectorThread.java:463) > ~[qpid-broker-core-6.0.1.jar:6.0.1] > at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown > Source) ~[na:1.8.0_51] > at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown > Source) ~[na:1.8.0_51] > at java.lang.Thread.run(Unknown Source) ~[na:1.8.0_51] > " > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
