Pete Bertrand commented on AMQ-5133:
------------------------------------

I believe I have been able to reproduce this issue, please see

>                 Key: AMQ-5133
>                 URL: https://issues.apache.org/jira/browse/AMQ-5133
>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.9.0
>         Environment: OS:CentOS release 6.5
> Java: 1.6.0_17, Java HotSpot 64-Bit Server VM
> Host: VMWare Xeon(R) CPU E5-2660 0; 4 core @2.2GHz
>            Reporter: Keith Oppenheim

> The Selector Worker: 0 thread is consuming 25% of the host CPU even though there are
no active producers or consumers and there are no messages in the message store.  I was able
to identify the offending thread by first using {{ps -eLF}} to find the ActiveMQ thread with
a relatively large and continually increasing amount of CPU time.  I then correlated the thread
ID (LWP  column  in {{ps}} output) to the native thread ID provided by the 'nid' value in
the thread dump.  At the time I ran {{ps}}, the Selector Worker thread had taken over 20 hours
of CPU time while the next closest ActiveMQ thread had taken 3 minutes of CPU time.  The Selector
Worker thread has nid=0x489 in the thread dump copied below.
> h4.  Steps To Reproduce
> Unfortunately, I don't have repeatable steps to reproduce.  I think the issue may have
occurred while I was purging a queue that had four active consumers.  The queue had several
thousand persistent 350KB messages.  The consumers were using selectors and all the messages
on the queue matched the consumers' selectors.  The consumers were Apache.NMS clients.  I
noticed the unexpected CPU usage after the purge completed, but I can't be sure it was triggered
by the purge.  I'm running performance tests and part of my normal test initialization requires
purging the queue.  As such, the purge is repeated many times a day and hasn't been an issue.
 After I noticed the CPU usage increase, I shut down all producers and consumers but the CPU
usage increase persisted.  I'm using JConsole to monitor the JVM and monitor/manage the broker.
