+- **Message**: `The length of execution output is over limit (around 4MB currently).`
+
+- **Cause**: The execution output is greater than 4 MB in size but the maximum supported output response payload size is 4 MB.
+
+- **Recommendation**: Make sure the execution output size does not exceed 4 MB. For more information, see [How to scale out the size of data moving using Azure Data Factory](https://docs.microsoft.com/answers/questions/700102/how-to-scale-out-the-size-of-data-moving-using-azu.html).

+
+- **Cause**: Too many activities are running concurrently. This can happen when too many pipelines are triggered at once.

+- **Cause**: The self-hosted integration runtime is offline or the Azure integration runtime is expired or not registered.
