Customer has about 300-over td jobs ( with data connector ).
So, they want to finish job quickly.
They want to use parallel execution all job.
But, Perfectqueue's limit is 96(default).
Therefore, Max-queue limit error has occured.
The customer split job-group (about 50-jobs) manually.
When many-jobs( over 100 ) are parallelized, wait for queueing by Workflow.
While we wait for a more comprehensive fix, we have increased our PerfectQueue limit to 256 items, up from a little under 100 items. We hope this will limit issues in the meantime, but we do believe this is an important fix for us to make in the future.
