JMS MDB Listener Queries

The JMS MDB listener is failing in PROD with the following error. Expecting a BytesMessage, received a message of type:

I understand that the root cause is due to the different in the message type. However i am trying to understand the processing of the listener.

And have the following queries.

  1. The queue depth of the topic is being shown as 1. Does that mean the listener is trying to process the same message again and again?
    If the listener has already consumed the message from the queue, shouldnt the message be removed from the queue.
  2. Is it due to enabling the "Container-managed transaction" setting in pega listener rule?
    How does this setting work? If the listener has already consumed the message then the message would have been removed from the queue.
    Where does pega store the message to re-process the same message.
  3. We have 2 nodes with 2 different subscribers listening to the same queue.
    Does that mean the 2 nodes will process the same message? Or only one of the node takes up the message.
    As we are noticing the above error in only one node.

Please revert back in case of any questions.
