Example scenario:

1. Queue has limited capacity 5 slots.

2. A lot of jobs are started in parallel at the same time via a workflow.

3. Every job has also Max Parallel check set to 1. 

4. Upon workflow start all jobs are activated. Even though queue is limited to 5, a lot more jobs start to execute exceeding 5 slots allocated.
