Benoit Xhenseval commented on AMQ-1990: --------------------------------------- We have this issue with 5.2 and 5.3-snapshot (18 April). The same application seems to be running ok under XP, OpenSolaris but throws those exceptions at a rate of 1 every minute or so under Ubuntu Server 8.10. HTH Benoit. > Failing network connectors randomly log SEVERE message : Could not accept > connection : java.lang.Object cannot be cast to > org.apache.activemq.command.Command > ------------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: AMQ-1990 > URL: https://issues.apache.org/activemq/browse/AMQ-1990 > Project: ActiveMQ > Issue Type: Bug > Components: Broker > Affects Versions: 5.1.0 > Environment: Linux, Windows XP, Mac OSX 10.5.1 > Reporter: Justin Pitts > Attachments: CouldNotAcceptConnection.java > > > I have an application which embeds the broker service. A common deployment > scenario is a sometimes-connected network of these applications. > Unfortunately, I don't have many situations where I can use discovery, so the > network connectors are static configurations. Randomly, when these network > connections are unable to connect, I see the following exception trace: > 30 Sep 2008 18:36:18 ERROR [ActiveMQ Transport Initiator: vm://instance-2#2] > (TransportConnector.java:234) - Could not accept connection : > java.lang.Object cannot be cast to org.apache.activemq.command.Command > These errors seem like they might be the result of a race condition during > start or stop of a network connector. I will attach a sample application > which demonstrates the problem. You may have to run the application a couple > times to provoke it. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
