"Failed to acquire the pool semaphore" during MDB invocation in JBoss EAP

Solution Verified - Updated -

Issue

  • When the container is attempting to deliver a JMS message to an MDB it reports "Failed to acquire the pool semaphore."
  • Can we put the second value equals to "1" with the annotation: @ActivationConfigProperty(propertyName = "maxSession", propertyValue = "1")}) in the MDB ?
