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

MEMORY000 - Details

• 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
