Smart SAP Assistant

• What is the cause and solution for SAP error message ADW056 - Serialization in shared objects terminated; insufficient memory space ?

  The SAP error message ADW056 indicates that there is an issue with serialization in shared objects due to insufficient memory space. This typically occurs in environments where the SAP system is trying to allocate memory for shared objects but cannot do so because the available memory is insufficient.
  Causes:
  
  Insufficient Memory Allocation: The system may not have enough memory allocated for the SAP application server or the database.
  Memory Leaks: There could be memory leaks in the application or in the underlying operating system, leading to reduced available memory over time.
  Configuration Issues: Incorrect configuration settings in the SAP system or the operating system can lead to memory allocation issues.
  High Load: A sudden increase in load on the SAP system can lead to temporary memory shortages.
  Shared Memory Limits: The operating system may have limits on the amount of shared memory that can be allocated.
  
  Solutions:
  
  
  Increase Memory Allocation:
  
  Check and increase the memory allocation for the SAP application server and database. This can be done through the SAP profile parameters (e.g., abap/heap_area_total, abap/heap_area_dia, etc.).
  Ensure that the operating system has sufficient physical and virtual memory available.
  
  
  
  Monitor and Optimize Memory Usage:
  
  Use transaction codes like ST02 (Tune Summary) and SM50 (Process Overview) to monitor memory usage and identify any processes that are consuming excessive memory.
  Optimize the code and configurations to reduce memory consumption.
  
  
  
  Check for Memory Leaks:
  
  Investigate the application for potential memory leaks. This may involve reviewing custom code or third-party add-ons that could be causing excessive memory usage.
  
  
  
  Adjust Operating System Settings:
  
  If you are on a Unix/Linux system, check the shared memory settings (e.g., shmmax, shmall, etc.) and increase them if necessary.
  On Windows, ensure that the system has adequate paging file size and that memory limits are not being hit.
  
  
  
  Restart the SAP System:
  
  In some cases, a simple restart of the SAP application server can help clear up memory issues temporarily.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for memory management and configuration best practices.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  System Monitoring Tools: Utilize SAP's monitoring tools (like Solution Manager) to keep track of system performance and memory usage over time.
  
  If the problem persists after trying the above solutions, it may be necessary to engage SAP support for further assistance.
