• What is the cause and solution for SAP error message RT546 - Frequency of system log messages in SAP application server ?

  The SAP error message RT546 indicates that the frequency of system log messages in the SAP application server has exceeded a predefined threshold. This can lead to performance issues and may indicate that the system is generating too many log messages, which can clutter the log and make it difficult to identify important messages.
  Cause:
  
  
  High Volume of Log Messages: The application server may be generating a high volume of log messages due to various reasons, such as:
  
  Excessive debugging or trace logging enabled.
  Frequent errors or warnings being logged by applications or background jobs.
  Misconfigured applications or processes that generate logs excessively.
  
  
  
  Configuration Settings: The threshold for log message frequency may be set too low, causing normal operations to trigger the error message.
  
  
  System Performance Issues: If the system is under heavy load or experiencing performance issues, it may lead to an increase in log messages.
  
  
  Solution:
  
  
  Review Log Messages: Analyze the system log messages to identify the source of excessive logging. Look for patterns or specific applications that are generating a high number of messages.
  
  
  Adjust Logging Levels: If debugging or trace logging is enabled, consider reducing the logging level to minimize the number of messages generated. This can be done in the transaction codes like SM37 (for job logs) or SM21 (for system logs).
  
  
  Check Application Configuration: Review the configuration of applications or background jobs that are generating excessive log messages. Ensure that they are not misconfigured or running unnecessarily.
  
  
  Increase Threshold: If the high volume of log messages is expected due to normal operations, consider increasing the threshold for log message frequency in the system settings. This can be done in the SAP system configuration.
  
  
  Monitor System Performance: Ensure that the system is performing optimally. Check for any performance bottlenecks that may be contributing to the issue.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message or provide additional guidance.
  
  
  Related Information:
  
  
  Transaction Codes: 
  
  SM21: To view system logs.
  SM37: To monitor background jobs and their logs.
  ST22: To check for dumps that may provide insight into issues causing excessive logging.
  
  
  
  SAP Documentation: Refer to the official SAP documentation for detailed information on logging and monitoring in SAP systems.
  
  
  Performance Monitoring Tools: Utilize SAP's performance monitoring tools (like ST03N) to analyze system performance and identify any issues that may be causing excessive logging.
  
  
  By following these steps, you should be able to identify the cause of the RT546 error message and implement a solution to mitigate the issue.
