• What is the cause and solution for SAP error message RT058 - Paging: Page out: Pages per second ?

  The SAP error message RT058, which refers to "Paging: Page out: Pages per second," typically indicates that the SAP system is experiencing excessive paging activity. This can occur when the system is running low on memory, leading to the operating system swapping data in and out of physical memory (RAM) to disk storage. This can significantly degrade performance.
  Cause:
  
  Insufficient Memory: The most common cause is that the SAP application server does not have enough physical memory (RAM) to handle the workload.
  High Workload: An increase in user load or background jobs can lead to higher memory consumption.
  Memory Leaks: Certain applications or processes may have memory leaks, causing them to consume more memory over time.
  Configuration Issues: Incorrect configuration of SAP parameters related to memory management can lead to inefficient memory usage.
  Database Activity: High database activity can also lead to increased memory usage, especially if the database is not optimized.
  
  Solution:
  
  Increase Physical Memory: If possible, add more RAM to the server to accommodate the workload.
  Optimize SAP Parameters: Review and optimize SAP memory parameters such as abap/heap_area_total, abap/heap_area_dia, and abap/heap_area_nondia to ensure efficient memory allocation.
  Monitor Workload: Use transaction codes like ST03N (Workload Analysis) to monitor the workload and identify any spikes or trends that may be causing high memory usage.
  Check for Memory Leaks: Use transaction ST02 (Tune Summary) to check for memory leaks in the system. If identified, consider restarting the affected processes or applications.
  Database Optimization: Ensure that the database is properly indexed and optimized to reduce memory consumption during queries.
  Review Background Jobs: Check for any unnecessary background jobs that can be scheduled during off-peak hours or removed altogether.
  Paging Configuration: Review the operating system's paging configuration to ensure it is optimized for SAP workloads.
  
  Related Information:
  
  Monitoring Tools: Use SAP monitoring tools like SAP Solution Manager or transaction codes ST06 (Operating System Monitor) and ST04 (Database Performance Monitor) to get insights into memory usage and performance.
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to memory management and performance tuning.
  System Logs: Review system logs (transaction SM21) for any related errors or warnings that could provide additional context to the paging issue.
  
  By addressing the underlying causes of excessive paging, you can improve the performance of your SAP system and reduce the occurrence of the RT058 error message.
