So the will remain in that state until that thread times out: "pmPublisherService-daemon-9" daemon prio=10 tid=0x00007fef4962c800 nid=0x3916 in Object.wait() [0x00007fef4c724000]    java.lang.Thread.State: TIMED_WAITING (on object monitor)      at java.lang.Object.wait(Native Method)      - waiting on <0x00000007122bc720> (a java.util.HashSet)      at org.jboss.remoting.transport.bisocket.BisocketClientInvoker.createSocket(BisocketClientInvoker.java:528)      - locked <0x00000007122bc720> (a java.util.HashSet)      at org.jboss.remoting.transport.socket.MicroSocketClientInvoker.getConnection(MicroSocketClientInvoker.java:1165)      at org.jboss.remoting.transport.socket.MicroSocketClientInvoker.transport(MicroSocketClientInvoker.java:816)      at org.jboss.remoting.transport.bisocket.BisocketClientInvoker.transport(BisocketClientInvoker.java:461)      at org.jboss.remoting.MicroRemoteClientInvoker.invoke(MicroRemoteClientInvoker.java:167)        <…>      - locked <0x000000072c411f78> (a java.lang.Object)      at org.jboss.messaging.core.impl.postoffice.MessagingPostOffice.routeInternal(MessagingPostOffice.java:2504)      at org.jboss.messaging.core.impl.postoffice.MessagingPostOffice.route(MessagingPostOffice.java:580) "pmPublisherService-daemon-8" daemon prio=10 tid=0x0000000040d07800 nid=0x3915 waiting for monitor entry [0x00007fef4c765000]    java.lang.Thread.State: BLOCKED (on object monitor)      at org.jboss.messaging.core.impl.ChannelSupport.handle(ChannelSupport.java:242)      - waiting to lock <0x000000072c411f78> (a java.lang.Object)      at org.jboss.messaging.core.impl.postoffice.MessagingPostOffice.routeInternal(MessagingPostOffice.java:2504) But it hangs very long: longer as timeout from in remoting-bisocket-service.xml: <attribute name="timeout" isParam="true">30000</attribute> (remoting-bisocket-service.xml) Any information you can provide me would be greatly appreciated!
