• What is the cause and solution for SAP error message CCMS_XMB053 - Exactly Once in Order messages that cause a short dump in qRFC ?

  The SAP error message CCMS_XMB053, which pertains to "Exactly Once in Order" (EOIO) messages in the context of qRFC (queued Remote Function Call), typically indicates that there is an issue with the processing of messages that are expected to be processed in a specific order. This can lead to short dumps if the system encounters problems while trying to process these messages.
  Cause:
  
  
  Message Processing Issues: The error often arises when there are issues with the processing of messages in the queue, such as:
  
  A message is stuck or has failed to process due to an error in the application logic.
  Dependencies between messages are not met, causing a blockage in the processing order.
  System resource issues, such as memory or database locks, that prevent the processing of messages.
  
  
  
  Configuration Issues: Incorrect configuration of the qRFC or EOIO settings can also lead to this error. This includes:
  
  Misconfigured logical destinations or RFC destinations.
  Issues with the configuration of the message types or queues.
  
  
  
  Database Locking: If a message is waiting for a database lock that is held by another process, it can lead to a situation where the message cannot be processed, causing a dump.
  
  
  Solution:
  
  
  Check the qRFC Monitor: Use transaction SMQ1 (for outbound queues) or SMQ2 (for inbound queues) to monitor the status of the queues. Look for any messages that are stuck or have failed.
  
  
  Analyze Short Dumps: Use transaction ST22 to analyze the short dumps. This will provide detailed information about the error, including the program and line number where the dump occurred.
  
  
  Reprocess Messages: If you find messages that have failed, you can attempt to reprocess them. This can be done by:
  
  Deleting the problematic messages if they are no longer needed.
  Manually triggering the processing of messages that are stuck.
  
  
  
  Check for Locks: Use transaction SM12 to check for any database locks that might be causing the issue. If you find locks that are not needed, you can release them.
  
  
  Review Configuration: Ensure that the configuration for qRFC and EOIO is correct. This includes checking the logical destinations and ensuring that all necessary settings are in place.
  
  
  System Resources: Monitor system resources to ensure that there are no bottlenecks. This includes checking memory usage, CPU load, and database performance.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide patches or updates that could resolve the issue.
  
  
  Related Information:
  
  EOIO Processing: Understand how EOIO processing works in SAP and the implications of message ordering.
  qRFC: Familiarize yourself with the qRFC framework and how it handles message queuing and processing.
  SAP Documentation: Refer to the official SAP documentation for detailed information on qRFC and EOIO configurations.
  
  By following these steps, you should be able to identify the root cause of the CCMS_XMB053 error and implement a solution to resolve the issue.
