After our upgrade, we find many of our jobs are stuck in Waiting. Only one job at a time is processing
Release : All Supported Clarity releases
Go to Administration - Reports and Jobs - and check each of the jobs that are Waiting and Processing at this time.
Make sure not many jobs are set to Incompatible to each other, creating a bottleneck and jobs will be stuck in Waiting until the Incompatible job completes.
We recommend to use default Incompatible jobs and only add them for a very specific reason.
