PeopleSoft PSJOB is triggered multiple times when in queued state after 8.61 upgrade

Hi All,

In one of our projects, we have recently upgraded from 8.59 tools version to 8.61. We are facing a unique issue which has become a very big blocker.

We have a push button where field change PeopleCode is triggering a PSJOB multiple times with a time gap of 20 secs. It triggers 8 instances of the same PSJOB using CreateProcessRequest.

Expectation:

job 1,2,3 will be executing and other 5 will be submitted one by one and will stay in queued state and when previous job is completed, next will process.

What is happening:

First few jobs are in processing state, next jobs are submitted and in queued state. The process normally takes around 4-5 mins to complete. Till this point, everything is normal.
