Agent group not assigning different Agents to Jobs started simultaneously

Products

• CA Automic Workload Automation - Automation Engine

Issue/Introduction

Error Message :
N/A

If multiple jobs are activated at the exact same time, Agent Group settings that would balance the distribution of the jobs (resource-based and Next) do not properly allocate the jobs to different Agents - instead, all will be assigned the same Agent. 

Investigation

Start an identical recurring task for three jobs, forcing adjustment on time range and with the same time range. All the jobs go into Generating status at once. Thus all the jobs get assigned the same agent.

Assign the jobs to a limited queue - this will force the jobs into a 'Waiting for Queue Slot' and will then assign them Agents correctly.
