If queries use a lot of temporary storage (e.g., large JOINs, GROUP BY, ORDER BY), the internal `tempdb` might run out of space, causing failures or severe slowdowns

slowdowns

If the issue persists and is not resolved by the above steps, contact Microsoft support with detailed logs and error messages

If your Fabric Data Warehouse is not responding for hours, it could be due to one of the following common issues:

Heavy query load or long-running queries causing resource exhaustion
Concurrency limits being hit if many users or processes are accessing it at once
Scheduled maintenance or service disruption in your region
Connectivity issues from your network or client tool

Check the Monitoring hub for query activity and the Fabric status page for any service outages. Restarting the warehouse or reducing workload might help temporarily.
