• What is the cause and solution for SAP error message STREX105 - Memory allocation failed ?

  The SAP error message STREX105, which indicates "Memory allocation failed," typically arises when the SAP system is unable to allocate the required memory for a process or operation. This can occur due to various reasons, including insufficient memory resources, configuration issues, or limitations in the underlying operating system.
  Causes:
  
  Insufficient Memory: The most common cause is that the SAP system does not have enough memory allocated to handle the current workload.
  Memory Leaks: Applications or processes that do not release memory properly can lead to memory exhaustion over time.
  Configuration Issues: Incorrect settings in the SAP memory management parameters (like abap/heap_area_dia, abap/heap_area_nondia, etc.) can lead to memory allocation failures.
  Operating System Limits: The operating system may impose limits on the amount of memory that can be allocated to a single process or the total memory available to the SAP instance.
  High Load: A sudden spike in user activity or background jobs can lead to temporary memory shortages.
  
  Solutions:
  
  
  Increase Memory Allocation:
  
  Review and increase the memory parameters in the SAP profile (e.g., abap/heap_area_dia, abap/heap_area_nondia, abap/heap_area_total).
  Ensure that the operating system has sufficient physical and virtual memory available.
  
  
  
  Monitor 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.
  Check for long-running transactions or background jobs that may be causing memory issues.
  
  
  
  Check for Memory Leaks:
  
  Analyze the code for any potential memory leaks, especially in custom ABAP programs or enhancements.
  Use tools like the ABAP Memory Inspector to identify and resolve memory leaks.
  
  
  
  Adjust Work Processes:
  
  Review the configuration of the work processes in the SAP instance. Adjust the number of dialog, background, and update work processes based on the system load and available resources.
  
  
  
  System Restart:
  
  In some cases, a system restart may help clear temporary memory issues, especially if the problem is due to a transient state.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address specific issues related to memory allocation failures.
  
  
  
  Related Information:
  
  SAP Memory Management: Understanding how SAP manages memory can help in configuring the system appropriately. SAP uses different memory areas for different types of processes (dialog, background, etc.).
  Transaction Codes: Familiarize yourself with transaction codes like ST02, SM50, SM66, and SM04 for monitoring and troubleshooting memory issues.
  SAP Basis Team: If you are not part of the SAP Basis team, it may be necessary to involve them for deeper analysis and configuration changes.
  
  If the problem persists after trying the above solutions, it may be beneficial to engage SAP support for further assistance.
