> Key: QPID-7024
> URL: https://issues.apache.org/jira/browse/QPID-7024
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Reporter: Keith Wall
> Assignee: Alex Rudyy
> 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. This problem does not cause a functional impact, but will consume more resources (threads + stack) than required.
