  • What is the cause and solution for SAP error message STREX049 - TREXRfcServer error (memory allocation failed) ?

    The SAP error message STREX049, which indicates a TREXRfcServer error due to memory allocation failure, typically arises in the context of SAP's Remote Function Call (RFC) interface. This error can occur for various reasons, including insufficient memory resources, configuration issues, or problems with the underlying operating system.

    Causes:

    1. Insufficient Memory: The most common cause is that the SAP system does not have enough memory allocated to handle the requests being made. This can happen if the system is under heavy load or if there are memory leaks in the application.
    2. Configuration Issues: Incorrect configuration settings in the SAP system or the operating system can lead to memory allocation failures.
    3. Resource Limits: Operating system-level resource limits (like ulimit settings in Unix/Linux) may restrict the amount of memory that can be allocated to processes.
    4. High Load: A sudden spike in the number of concurrent users or processes can lead to memory exhaustion.
    5. Bug in SAP Kernel: Sometimes, specific versions of the SAP kernel may have bugs that lead to memory allocation issues.

    Solutions:

    1. Increase Memory Allocation:

      • Check the current memory settings in the SAP system and consider increasing the memory allocation for the instance.
      • Adjust the parameters in the instance profile, such as abap/heap_area_dia, abap/heap_area_nondia, and rdisp/PG_MAXFS to allow for more memory usage.
    2. Monitor System Resources:

      • Use transaction codes like ST06 or SM04 to monitor memory usage and identify any bottlenecks.
      • Check for any long-running processes or background jobs that may be consuming excessive memory.
    3. Review Configuration:

      • Ensure that the SAP system and the operating system are configured correctly for optimal performance.
      • Check the operating system's resource limits (e.g., ulimit settings on Unix/Linux) and adjust them if necessary.
    4. Patch and Update:

      • Ensure that your SAP system is up to date with the latest patches and updates, as these may contain fixes for known issues related to memory allocation.
    5. Restart the Instance:

      • If the issue persists, consider restarting the SAP instance to clear any memory leaks or temporary issues.
    6. Consult SAP Notes:

      • Search for relevant SAP Notes in the SAP Support Portal that may address this specific error or provide additional troubleshooting steps.
    7. Contact SAP Support:

      • If the problem continues after trying the above solutions, it may be necessary to contact SAP Support for further assistance, especially if it appears to be a bug or a deeper system issue.

    Related Information:

    • Transaction Codes: Use transaction codes like ST22 (Dump Analysis) to check for any dumps related to memory issues.
    • System Logs: Review system logs (SM21) for any related error messages that could provide more context.
    • Performance Monitoring: Regularly monitor system performance and memory usage to proactively address potential issues before they lead to errors.

    By following these steps, you should be able to diagnose and resolve the STREX049 error effectively.
