Description

An agent starts a time based camel route for each JP it launches. This route wakes a thread and collects metrics for the child process. This happens at regular intervals. When a child process terminates, the agent should stop associate route. In some cases routes keep running and accumulating in memory causing a leak which lead to OOM. Modify code to force route termination when the process is dead yet agent keeps trying to collect metrics for it.
