Power BI Refresh Error:
UserErrorSelfHostedIntegrationRuntimeBusyWithFullTask

What does this error mean?

The SHIR node is at capacity — all concurrent job slots are occupied. New activities queue until a running activity completes.

Common causes

  • 1The number of concurrent copy or data flow activities exceeds the SHIR node's configured concurrent job limit
  • 2Long-running activities are blocking all slots, preventing new activities from starting
  • 3Only one SHIR node is configured and it is handling too many simultaneous pipeline runs
  • 4The SHIR machine has insufficient CPU or memory, causing individual jobs to run slower

How to fix it

  1. 1Increase concurrent jobs: open the IR configuration tool > Settings > Max concurrent jobs.
  2. 2Add additional SHIR nodes to scale out capacity horizontally.
  3. 3Cancel stuck or long-running activities in ADF Monitor that are blocking slots.
  4. 4Optimize heavy copy activities (parallelism, partition strategy) to complete faster.
  5. 5Upgrade the SHIR host's CPU and RAM if it is consistently at capacity.

Frequently asked questions

Does a self-hosted integration runtime failure affect all pipelines using it?

Yes — all pipelines routed through the affected SHIR fail simultaneously.

How do I check the health of a self-hosted integration runtime?

Open Microsoft Integration Runtime Configuration Manager on the SHIR host. The Status tab shows connection state and version. ADF Studio also shows SHIR health under Manage > Integration Runtimes.

What ports does a self-hosted integration runtime need outbound access to?

Outbound HTTPS (port 443) to *.servicebus.windows.net and *.core.windows.net. Individual connectors may need additional ports — SQL Server: 1433, FTP: 21.

Can I have multiple nodes in a self-hosted integration runtime for redundancy?

Yes — up to four nodes per SHIR. If one goes offline, ADF routes to a healthy node. Use at least two nodes for production pipelines.
