Environment

Release : 21.x

Component : Automation Engine, OS Agent

Cause

By design when JCP is not yet started.

Resolution

The behavior of the agent are the following:

-If during startup system is not available , the AGENT must end


-If during operation - connection is lost - AGENT must re-connect as defined until the process is ended.

 
It is a normal behavior since the JCP has not yet started.
