Hi,
My name is Arsene. I’m using camunda.spring.boot.starter.version 3.3.6. When executing my workflow, I’m getting the below error message. I have a thread pool of 20. I submitted and started around 400 process instances. Shouldn’t the job be queued in DB and handled when there is a worker thread available?
Any suggestions for this?
