Hi

All other threads are waiting for lock <0x471a79e0> and yes, it is locked by the following thread in:


  |            - locked <0x471a79e0> (a com.cisco.nm.cmp.gjc.cm.UserConnectionImpl)
  |             at com.cisco.nm.cmp.gjc.cm.GWCommandListenerImpl.send(GWCommandListenerImpl.java:207)
  | 
  | 

But, I still can't understand why this thread is waiting on 


  |             at java.lang.Object.wait(Native Method)
  |             - waiting on <0x47080560> (a EDU.oswego.cs.dl.util.concurrent.WriterPreferenceReadWriteLock$ReaderLock)
  |             at java.lang.Object.wait(Object.java:474)
  |             at EDU.oswego.cs.dl.util.concurrent.WriterPreferenceReadWriteLock$ReaderLock.acquire(WriterPreferenceReadWriteLock.java:163)
  |             - locked <0x47080560> (a EDU.oswego.cs.dl.util.concurrent.WriterPreferenceReadWriteLock$ReaderLock)

  |             at org.jboss.messaging.core.impl.postoffice.MessagingPostOffice.route(MessagingPostOffice.java:489)
  |             at org.jboss.jms.server.endpoint.ServerConnectionEndpoint.sendMessage(ServerConnectionEndpoint.java:741)
  |             at org.jboss.jms.server.endpoint.ServerSessionEndpoint.send(ServerSessionEndpoint.java:383)
  | 

While no other thread is holding 0x47080560

Can you please advise?
