[jboss-user] [JBossMQ] - MDB stops servicing any messages (ReceiversCount goes to 0)

Environment Jboss 4.2.2 OS RHEL 4.0 JDK 5.0 Question: I have very simple MDB implementation where I log some data into db asyncrhonously. This implementation works fine except sometimes, it runs to a situation where-in ReceiversCount on the Queue goes to 0 and QueueDepth increases. (a) When would the RecieversCount go to zero? ie. the only one receiver associated with this queue is empty or null (b) When I look into the logs I see javax.resource.ResourceException: Interrupted while requesting permit! Waited 0 ms logged in server.log This seems like the thread is already in interrupted state or being interrupted when a simple getConnection() request is made. Below is stack trace 2008-09-14 15:57:51,180 ERROR [org.jboss.resource.adapter.jms.JmsSessionFactoryImpl] could not create session javax.resource.ResourceException: Interrupted while requesting permit! Waited 0 ms at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.getConnection(InternalManagedConnectionPool.java:309) at org.jboss.resource.connectionmanager.JBossManagedConnectionPool$BasePool.getConnection(JBossManagedConnectionPool.java:500) at org.jboss.resource.connectionmanager.BaseConnectionManager2.getManagedConnection(BaseConnectionManager2.java:341) at org.jboss.resource.connectionmanager.TxConnectionManager.getManagedConnection(TxConnectionManager.java:315) at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:396) at org.jboss.resource.connectionmanager.BaseConnectionManager2$ConnectionManagerProxy.allocateConnection(BaseConnectionManager2.java:842) at org.jboss.resource.adapter.jms.JmsSessionFactoryImpl.allocateConnection(JmsSessionFactoryImpl.java:389) at org.jboss.resource.adapter.jms.JmsSessionFactoryImpl.createSession(JmsSessionFactoryImpl.java:369) So, the final question, is are (a) and (b) related? if so, what is the solution? I think I gave all info but could add more. Any help is greatly appreciated. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4176393#...
