How to fix this error?

Procedure for System Administrators

PROC memory is process-local memory which belongs to a work process and
which is not associated with a user session. Technically, PROC memory is
supplied to a work process via standard OS heap memory allocation, but
SAP ABAP application server keeps track of the consumed amount.
Above value is the sum of PROC memory across all work processes.

• What is the cause and solution for SAP error message MEMORY000 - Peak value for PROC memory since startup ?

  The SAP error message "MEMORY000 Peak value for PROC memory since startup" indicates that the process memory usage of an SAP instance has reached a peak value that is noteworthy, often suggesting that the memory consumption is high. This can lead to performance issues or even system instability if not addressed.
  Causes:
  
  High Workload: Increased user activity or background jobs can lead to higher memory consumption.
  Memory Leaks: Certain transactions or programs may not release memory properly, leading to gradual increases in memory usage.
  Configuration Issues: Incorrectly configured memory parameters in the SAP system can lead to inefficient memory usage.
  Large Data Processing: Operations that involve processing large datasets can temporarily spike memory usage.
  Inefficient ABAP Code: Poorly optimized ABAP programs can consume excessive memory.
  
  Solutions:
  
  Monitor Memory Usage: Use transaction codes like ST02 (Tune Summary) and SM04 (User Overview) to monitor memory usage and identify which processes are consuming the most memory.
  Analyze Workload: Check for any unusual spikes in workload or user activity that may correlate with the memory peak.
  Review ABAP Code: Analyze and optimize any custom ABAP programs that may be causing high memory usage.
  Adjust Memory Parameters: Review and adjust the instance profile parameters related to memory, such as abap/heap_area_dia, abap/heap_area_nondia, and enque/table_size.
  Restart the Instance: If memory usage is consistently high and cannot be resolved through other means, consider restarting the SAP instance to clear memory.
  Patch and Upgrade: Ensure that your SAP system is up to date with the latest patches and upgrades, as these may contain fixes for memory-related issues.
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to memory management and performance tuning for specific guidance and best practices.
  SAP Community: Engage with the SAP Community for insights and experiences from other users who may have faced similar issues.
  Performance Tuning: Regularly perform system performance tuning and monitoring to prevent memory-related issues from arising.
  
  Conclusion:
  Addressing the "MEMORY000" error involves a combination of monitoring, analysis, and potential configuration changes. Regular maintenance and performance tuning can help mitigate the risk of high memory usage in SAP systems.
