[jira] [Created] (UIMA-4360) DUCC Agent camel route shutdown hangs a thread trying to stop a JP

Jerry Cwiklik created UIMA-4360:
-----------------------------------

             Summary: DUCC Agent camel route shutdown hangs a thread trying to stop a JP
                 Key: UIMA-4360
                 URL: https://issues.apache.org/jira/browse/UIMA-4360
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.0.0-Ducc


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.
