Data Factory Runtime Busy Error (9518) in Copy Data Activity, but Same Connection Works in Dataflow
Hi Team,
Thank you for your guidance.
We reviewed the Integration Runtime logs and found repeated errors:
"Not enough resources to start a new worker. Current workers count: 0."
After investigating the gateway server, we found that several applications were running and consuming server resources. We stopped the unnecessary applications and retried the connection test.
After freeing up server resources, the Copy Data Activity and connection test started working successfully.
This confirms that the issue was related to insufficient resources on the server hosting the On-Premises Data Gateway / Integration Runtime, preventing worker processes from being created.
Thank you for helping us identify the root cause. 😊😊😘😘
hi NuwanAthukorala Most likely, this is a gateway cluster node / Integration Runtime problem, not a Fabric platform issue. Start with switching nodes or bumping up resources, and you'll likely be good.
This is because a similar issue was raised here and was resolved by changing / bumping up node resources:

Appreciate if you can 'Kudos' and/or 'Accept as Solution' if this answered your query.
Since the same gateway and source work successfully through Dataflow Gen2, could you clarify whether Copy Data Activities use a different Integration Runtime path or gateway execution mechanism that might explain Error 9518?
