App reloads in SaaS edition of Qlik Sense 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 SaaS 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 detail there is a limit for each app file, but during reload, additional memory is typically required to process calculation before the app's data model has been updated.
During a reload the Engine will periodically measure allocated memory. If the allocated memory reached the reload limit the reload will fail with a memory exceeded error.
