<div class="jive-rendered-content"><p>Hi,</p><p>I'm having an issue where a remote client call to createQueueConnection that hangs and never returns until a socket timeout.</p><p>We are using JBoss 4.2.3GA, Messaging 1.4.4, Remoting 2.2.3SP3.  The system involves 500+ remote client machines sending 500K+ messages a day to a Queue with a message listener attached.  There are a few other minor JMS queue activities as well.</p><p>It runs well until about once a day, usually during heavy load, all the clients hang, requiring a restart of the server.  The CPU runs at 20% with plenty of heap and a strong Oracle box.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>At this point I'm trying to figure out if I have a remoting configuration mistake, a client code mistake, a possible remoting bug, or just a limitation of the architecture during a high stress point.  In the client, I don't re-use any of the JMS objects from one send to the next.  I haven't been able to reproduce in a development environment yet.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I did try to back out the change made in JBREM-1081 to ServerInvoker in 2.2.3 to look like the 2.5.4 version of getCallbackHandler.  It did removed the BLOCKED threads I show below, but it still fails somewhere in the ServerInvokerCallbackHandler.connect() call, probably in BisocketClientInvoker.handleConnect().  My client is reluctant to turn on trace mode in production so I'll continue to add custom logging until I track this down. My next configuration change will be trying a smaller pingFrequency.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The remote client side Thread dump looks like this.</p><p>3XMTHREADINFO      "SEQMsgHandling" (TID:0x094A4800, sys_thread_t:0x094C9FB0, state:R, native ID:0x00007B14) prio=5</p><p>4XESTACKTRACE          at java/net/SocketInputStream.socketRead0(Native Method)</p><p>4XESTACKTRACE          at java/net/SocketInputStream.read(SocketInputStream.java:155(Compiled Code))</p><p>4XESTACKTRACE          at java/io/BufferedInputStream.fill(BufferedInputStream.java:229(Compiled Code))</p><p>4XESTACKTRACE          at java/io/BufferedInputStream.read(BufferedInputStream.java:246(Compiled Code))</p><p>4XESTACKTRACE          at java/io/FilterInputStream.read(FilterInputStream.java:89(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/remoting/transport/socket/MicroSocketClientInvoker.readVersion(MicroSocketClientInvoker.java:1077(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/remoting/transport/socket/MicroSocketClientInvoker.transport(MicroSocketClientInvoker.java:682(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/remoting/transport/bisocket/BisocketClientInvoker.transport(BisocketClientInvoker.java:458(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/remoting/MicroRemoteClientInvoker.invoke(MicroRemoteClientInvoker.java:141(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/remoting/Client.invoke(Client.java:1925(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/remoting/Client.addCallbackListener(Client.java:1994(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/remoting/Client.addListener(Client.java:1158(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/jms/client/remoting/JMSRemotingConnection.addInvokerCallbackHandler(JMSRemotingConnection.java:259(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/jms/client/remoting/JMSRemotingConnection.start(JMSRemotingConnection.java:388(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/jms/client/delegate/ClientConnectionFactoryDelegate.org$jboss$jms$client$delegate$ClientConnectionFactoryDelegate$createConnectionDelegate$aop(ClientConnectionFactoryDelegate.java:165(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/jms/client/delegate/ClientConnectionFactoryDelegate$createConnectionDelegate_N3019492359065420858.invokeNext(ClientConnectionFactoryDelegate$createConnectionDelegate_N3019492359065420858.java(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/jms/client/container/StateCreationAspect.handleCreateConnectionDelegate(StateCreationAspect.java:80(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/aop/advice/org/jboss/jms/client/container/StateCreationAspect0.invoke(StateCreationAspect0.java(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/jms/client/delegate/ClientConnectionFactoryDelegate$createConnectionDelegate_N3019492359065420858.invokeNext(ClientConnectionFactoryDelegate$createConnectionDelegate_N3019492359065420858.java(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/jms/client/delegate/ClientConnectionFactoryDelegate.createConnectionDelegate(ClientConnectionFactoryDelegate.java(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/jms/client/JBossConnectionFactory.createConnectionInternal(JBossConnectionFactory.java:205(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/jms/client/JBossConnectionFactory.createQueueConnection(JBossConnectionFactory.java:101(Compiled Code))</p><p>4XESTACKTRACE          at org/jboss/jms/client/JBossConnectionFactory.createQueueConnection(JBossConnectionFactory.java:95(Compiled Code))</p><p>...</p><p style="min-height: 8pt;
