Subject AMQ 100% of CPU in RCP application
Date Wed, 19 Dec 2007 10:57:32 GMT

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

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
