I'm using tomcat 6 and HypericHQ for monitoring via JMX.
I don't know if this is an hyperic issue or not, but i wonder if there is an option to fix it via tomcat/java configuration. the reason that i don't know if this is an hyperic or a tomcat/java configuration issue is because that when we use hyperic on other standard java daemon it doesn't have the same connection leak issue.
the issue is the following:
hyperic, overtime, opens hundreds of jmx connection and never closes them.. after few hours our tomcat server is using 100% cpu without doing anything.
once i stop hyperic agent, tomcat will go back to 0-1% cpu..
here is what we are seeing virtual vm: http://forums.hyperic.com/jiveforums/servlet/JiveServlet/download/1-11619-37096-2616/Capture.PNG
is there any thing that we can do to fix this via java configuration? (forcing it to close a connection that is open for more than X seconds?)
One more thing, in tomcat we see (from time to time) the following message (while hyperic is running):
