  The SAP error message CRMS4_PS_NET164 indicates an internal error related to clearing the memory of the central buffer layer. This type of error can occur in various scenarios, often related to performance issues or memory management within the SAP system.
  Causes:
  
  Memory Management Issues: The error may arise due to insufficient memory allocation for the central buffer layer, leading to difficulties in clearing or managing memory.
  System Load: High system load or concurrent processing can lead to contention for memory resources, causing internal errors.
  Corrupted Buffer: There may be corruption in the buffer data, which can lead to failures when the system attempts to clear or manage the buffer.
  Configuration Issues: Incorrect configuration settings for the buffer or memory management parameters can also lead to this error.
  
  Solutions:
  
  Check System Resources: Monitor the system's memory usage and ensure that there is sufficient memory allocated for the central buffer layer. You may need to increase the memory allocation if it is consistently low.
  Restart the Application Server: Sometimes, a simple restart of the application server can clear temporary issues and reset the buffer.
  Clear Buffer Manually: You can try to clear the buffer manually using transaction codes like SM12 (to delete lock entries) or SM21 (to check system logs for errors).
  Review Configuration Settings: Check the configuration settings related to memory management in the SAP system. Ensure that parameters such as abap/buffersize and abap/heap_area_total are set appropriately.
