This looks like it might be a bug - but ActiveMQ 5.0 is now available
- please give it a try ;)

Hi,
Im running an eclipse RCP application that uses AMQ4.1.1 for
receiving data
from temp queues(request/response) and topics (for updates). We are
having
trouble with CPU on client side and from using YourKit profiler to
monitor
this over about 16 hours I see that AMQ is 100% of the time.
According to
the snapshot attached, my methods are completely negligible. Here is
a quick
snippet:

318,332,979 java.lang.Thread.run() 100 %

This seems strange since its an RCP application with glazed lists
etc. I
would have thought that my methods (or at least eclipse/glazed lists
would
be chewing up the CPU). But from this it seems to be AMQ.
Does anyone have any thoughts on this or am I reading this data
incorrectly?
Thanks for any input
