Hi,

we are facing  exaclty the same issue in JBoss EAP 5.1 with JBoss Remoting 
2.5.3SP1.patch01 
Thread dumps show many threads in BLOCKED state all waiting for an object that 
is locked by a thread in TIMED_WAITING state. 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)

org.jboss.remoting.transport.socket.MicroSocketClientInvoker.getConnection(MicroSocketClientInvoker.java:1165)

"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!

Best regards,
Vadim
