High CPU Usage on restarting the Tomcat 7.0.39
We are using Tomcat 7.0.39 ((java version "1.7.0_25"), and Sometimes
CPU goes high when we restart the TOMCAT.
We have to stop the Tomcat in-order to release the release resources
and again restarting the Tomcat fixes the problem.
On profiling, found that Invocations on
sum.rmi.transport.tcp.TCPTransport$ConnectionHandler.run() keep on
getting increased and occupy more CPU.
Please find attachment for more information. Any help/clue on this is
appreciated.

I can get the thread dump if it is needed to figure out the root cause.
Thanks for the help!
