Problem
Solution
Kill the runnable using the kill command. For example kill abs_m. Try starting it again with the start command, for example, start abs_m.
If the output of the list command shows one or more runnables in state FAILED or STOPPED. Type startall. Once the command finishes give the runnables some time to complete startup and type list to see their current state.
If a runnable is DEACTIVATED, activate the runnable again.
