Hello
I am using ActiveMQ4.1.1 and running the Master/Slave Setup and to test it i run the receivers in my clustered environment and the producer on my local machine when i bring the Master down my producer sometimes hangs. I also have a TransportListener that is not getting notified. Here is the Thread dump main" prio=6 tid=0x0003de48 nid=0x1420 in Object.wait() [0x0007f000..0x0007fc3c] at java.lang.Object.wait(Native Method) - waiting on <0x02b50068> (a edu.emory.mathcs.backport.java.util.concurrent.locks.CondVar) at java.lang.Object.wait(Object.java:474) at edu.emory.mathcs.backport.java.util.concurrent.locks.CondVar.await(CondVar.java:75) - locked <0x02b50068> (a edu.emory.mathcs.backport.java.util.concurrent.locks.CondVar) at edu.emory.mathcs.backport.java.util.concurrent.ArrayBlockingQueue.take(ArrayBlockingQueue.java:318) at org.apache.activemq.transport.FutureResponse.getResult(FutureResponse.java:42) at org.apache.activemq.transport.ResponseCorrelator.request(ResponseCorrelator.java:75) at org.apache.activemq.ActiveMQConnection.syncSendPacket(ActiveMQConnection.java:1175) at org.apache.activemq.ActiveMQSession.send(ActiveMQSession.java:1551) at org.apache.activemq.ActiveMQMessageProducer.send(ActiveMQMessageProducer.java:465) at org.apache.activemq.ActiveMQMessageProducer.send(ActiveMQMessageProducer.java:356) Manish. -- View this message in context: http://www.nabble.com/Proucer-Hanging....-cause---syncSendPacket-tf4243107s2354.html#a12074021 Sent from the ActiveMQ - User mailing list archive at Nabble.com.
