AE: Calculation of Agent Resources is incorrect

Products

• CA Automic Workload Automation - Automation Engine

Issue/Introduction

Since AE 12.2.1 the calculation of agent resources does not work correctly in the following scenario:

A JOBS resource consumption is not allocated because this information has not been sent to the agent (e.g. the job has ended for example with status: ENDED_INACTIVE or FAULT_OTHER, ENDED_EMPTY, etc. )

Under this circumstances, the AE erroneously releases the resources when it should not, which allows other JOBS that should be waiting for resources to be started when they should not.

Please note that the issue only appears when "Generate at Runtime" is activated
