Restricting workers for parallel exec steps does not work as expected

Created: 03/Jan/19 12:48 PM   Updated: 04/Jan/19 02:22 AM
Component/s: None
Affects Version/s: 8.0.29

 Description  « Hide
Situation:
Parallel execution step running some script on several nodes in parallel, parameterized with workers equal to e.g. 2.

Expected:
I'd expect to see a maximum of <workers> (e.g. 2) steps running simultaneously and another one started as soon as one of them is done.

Actual:
It seems to work fine for the first group, i.e. for workers set to 2 just two steps are started initially and as soon as those are done another two are started; but when they start running everything else seems to be triggered at once (meaning as fast as qb/the node can handle it - until the node runs out of memory in this case).
