Which job get the resource when it's released?
I would like to know details about how a resource is assigned to a job. I found the following KB article: https://electriccloud.zendesk.com/entries/242052-KBEC-00152-Commander-step-scheduler-algorithm I think it's helpful. However I also would like to know which job gets the resource in case several jobs are waiting for a resource. Giving the following preconditions:
- a resource "A" which has a step limit of 1
- resource "A" is busy with job "jobA"
- jobs "jobB", "jobC" and "jobD" are started one by one with an interval of 30 seconds. These jobs would like to use resource "A" in their step setting and there's no exclusive or time limit setting in the steps
say after 5 minutes, "jobA" releases resource "A" Can you tell me which job get resource "A"?

Job priorities take effect when two or more job steps in different jobs are waiting for the same resource. When the resource is available, it will be used by the job step that belongs to the job with the highest priority. If the priority level is the same, the resource will be used by the job step that belongs to the job with the lowest job ID number (i.e. the oldest job). If the job steps are in the same job, the resource will be used first by the step with the lowest job step ID number.
