App reloads in Qlik Cloud fail with the below error message:
Data has not been loaded. Please correct the error and try loading again.
The following error occurred: The memory limit for the request was reached
Resolution
There are three main directions on mitigating high memory allocation problems;
- Review data load script
- Remove unused fields and rows for being loaded
- Drop tables when no longer needed in the data processing
- Implement incremental loads to optimize volume of data being processed
- Utilize optimized QVD loads
- Add more capacity to the tenant to allow for heavier workload
- Expanded apps
- Dedicated capacity
- Schedule a reload instead of using a manual/interactive one. In this case, the reload will be assigned to a proper reload engine.
Cause
The Qlik Sense Engine in Qlk Cloud is configured to have a sandbox limit for reloads so that they do not expand infinitely and bring down the Engine running the reload. Based on subscription details there is a limit for each app file. Still, additional memory is typically required during reload to process calculations before the app's data model has been updated.
During a reload the Engine will periodically measure allocated memory. If the allocated memory reaches the reload limit the reload will fail with a memory exceeded error.
