Conductor waits more than an hour to schedule the next task.

[adrichem]

Describe the bug Tasks with an execution time of several minutes complete successfully, but the next task is not scheduled until approx. an hour and a half later. The worker is running and idle. The task queue has a size of 0 and shows the working polling every second.

Whenever I execute the workflow below, the tasks in fork all run fine, The first tasks in each parallel path of fork_2 complete but the no-op-worker-SET2-1-2 and no-op-worker-SET2-2-2 tasks don't execute. The execution tab in the UI shows them with status 'Not executed'

Details Conductor version: Tried 3.18.0 and 3.19.0

Running based on Running Conductor Using Docker for evaluation and demo purposes.

On the Orkes playground, these type of workflows are running fine. I checked the documentation, but did not find anything that seemed relevant to configure.

Workflow definition: Here's a workflow that demonstrates the issue.

To Reproduce The no-op-worker sleeps for for requested Time and return completed state. Its instantiated like this: [WorkerTask(taskType: "no-op-worker", batchSize: 100, domain: null, pollIntervalMs: 200, workerId: "deploy-worker")]

Expected behavior I expect the next task to be scheduled for execution when its predecessor completes.
