[jira] [Created] (QPID-7024) BDB HA - Group change thread-pool sized to availableProcessors +1

Keith Wall created QPID-7024:
--------------------------------

             Summary: BDB HA - Group change thread-pool sized to availableProcessors +1
                 Key: QPID-7024
                 URL: https://issues.apache.org/jira/browse/QPID-7024
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
            Reporter: Keith Wall
            Priority: Minor


The BDB HA implementation internally uses a thread pool to process group change events.  This thread pool is sized to {{Runtime.getRuntime().availableProcessors() + 1}}.  On a machine with many cores, this will create a very large number of threads.

There is probably no reason why this thread pool needs to be quite so large.
