Subject [jira] [Closed] (UIMA-3718) DUCC Agent accumulates Camel Routes Leading to OOM
Date Wed, 02 Apr 2014 19:28:17 GMT

     [ https://issues.apache.org/jira/browse/UIMA-3718?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jerry Cwiklik closed UIMA-3718.

    Resolution: Fixed

Modified code to make sure that the agent removes Camel route associated with a process when
it exits. Added additional logging to show active routes after process route is removed.

> When an agent launches a new process it creates a Camel route to collect stats (memory
usage, cpu, etc). The route is added to the Camel context where it remains for the lifetime
of the agent. When the process is stopped, the agent only stops the route but never removes
it from the Camel context. Over time these routes accumulate and eventually cause Agent OOM.
> When the process is stopped the agent should remove associated route from Camel context.
