Description

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.
