I'm having issues with some workers not picking up tasks. Here's my setup: • Prefect version: 3.4.0 • Work pool:

windows-workers

(process type) • Workers: 5 workers all online with limits of 5 concurrent flows each • Problem: Some workers (like PVE2-LBT-009) are handling multiple flows simultaneously, while others (like PVE2-LBT-001) only pick up 1 flow and then stop, even though they show 0/5 active slots in the concurrency limits dashboard. What I've checked: • All workers are using the same work pool (

windows-workers

) and work queue (

default

) • No custom concurrency limits are set (confirmed with

prefect concurrency-limit ls

) • Workers are started with

--limit 5

and show as online • Flows are backing up with some running late while workers appear idle Questions: 1. Are there any Hobby Tier limits on total concurrent flows across all workers that might cause this behavior? 2. Could this be related to worker slot management not properly releasing capacity? 3. Any known issues with process-type work pools and worker load balancing? The inconsistent worker utilization suggests either a tier limitation or a worker polling/slot management issue. Any insights would be appreciated!

you might be encountering rate limits potentially? have you checked the worker logs?
