3265963 - Failed to persist specific View through Task Chain - Cannot allocate enough memory

• A View persistency fails with the "cannot allocate enough memory" error or "Possible reasons could be: restart of server due to some technical issues, lost database connection, an exception in a remote source etc.", when the job starts through a Task Chain.
• When executed individually, the data gets persisted without errors.

• SAP Datasphere

1. Access the affected SAP Datasphere tenant;
2. Add the Graphical View into a Task Chain;
3. Run the Task Chain through the Data Integration Monitor;
4. The load will fail and stop when persisting the View that you added in step 2.

• Design issue and/or performance issue due to other competing tasks. 

The possible workarounds are:

1. Add more partitions to the affected View, more information in SAP Help Portal Documentation: Creating Partitions for Your Persisted Views
   
   • OR
2. Check the configured Run Mode option and test the behavior with the other mode selected (Performance-Optimized or Memory-Optimized), more information in SAP Help Portal Documentation: Data Persistence and Processing Mode. 
   Note: this might not work and is heavily dependent on the size of the dataset that is being processed.
