title: Message Driven Bean (MDB) running on Websphere Application Server, leaves channel connections open
body: <p>Hi
  I have two Message Driven Beans (MDBs) running on Websphere Application Server v7.
  It is connecting to, and receiving messages from Websphere MQ v6.
  On the Queue Manager, we notice that the number of open channel connections keeps on growing, and appears as though the MDBs are not releasing these connections.
  I am not aware of any errors happening in the onMessage method of the MDBs which could cause it to not exit cleanly.</p>
  
  <p>Any advise on what could be causing this would be greatly appreciated
  Thanks
  Gavin</p>
