Hi shoefried , Thank you for reaching out to the Microsoft Community Forum.

This issue likely stems from ADLS Gen 2 throttling, network issues, or ADF service timeouts. To fix, add a timeout and retry policy (3 retries, 30s delay) to each activity, check ADLS metrics for throttling or errors in Azure Monitor, ensure your Integration Runtime is healthy, and enable detailed ADF logs via Diagnostic Settings.

If the above doesn’t resolve your issue, contacting Microsoft support and raising a support ticket with them is the best solution as suggested by lbendlin . Make sure to provide them with all the troubleshooting steps you've already taken to help them understand the issue better and provide a solution.
