> Project: UIMA
> Issue Type: Bug
> Components: DUCC

>
> The agent tries to access /proc/PID/statm and also tries to collect metrics
> via JMX from a process that may no longer be running producing exceptions in
> an agent log. The process metric collector runs at regular interval in a
> dedicated thread driven by a camel timer route. There seems to be a race
> condition when a process exits and before an agent can change its internal
> state, the metric collector thread attempts to access statm which is no
> longer in there.
> When an exception is caught, check the state of the process and if it is not
> running dont log an exception
