> It looks like a thread trying to stop a JP hangs in the following code (NodeAgent.java):
>    	  // stop collecting process stats from /proc/<pid>/statm
>           super.getContext().stopRoute(pid);
> The thread is stuck in stopRoute() until the JP is killed via -9. This hang does not happen every time but seems to happens sometimes.
