This error can occur in various scenarios, such as during the execution of programs, transactions, or when the system is trying to allocate memory for certain operations.
  Causes:
  
  Insufficient Memory: The most common cause is that the SAP system has run out of available memory, particularly in the context of page-free memory.
  Configuration Issues: Incorrect configuration settings for memory management in the SAP system can lead to this error.

  Increase Memory Allocation: If the system is running out of memory, consider increasing the memory allocation for the SAP instance. This can be done through the SAP profile parameters (e.g., abap/heap_area_total, abap/heap_area_dia, etc.).
  Check Configuration: Review the memory management settings in the SAP system to ensure they are configured correctly. This includes checking parameters related to paging and memory allocation.

  Database Optimization: Ensure that the database is optimized and that there are no issues affecting its performance. This may involve checking for locks, long-running queries, or other database-related problems.
