• What is the cause and solution for SAP error message ICM528 - Number of suppressed entries ?

  The SAP error message ICM528, which states "Number of suppressed entries," typically occurs in the context of the Internet Communication Manager (ICM) when there are too many log entries being generated, and the system suppresses some of them to avoid performance issues or excessive log file sizes.
  Cause:
  
  High Volume of Log Entries: The ICM is generating a large number of log entries, which can happen due to high traffic, frequent errors, or extensive logging settings.
  Configuration Settings: The logging level might be set too high, causing the system to log more information than necessary.
  Performance Issues: The system may be experiencing performance issues, leading to the suppression of log entries to maintain stability.
  
  Solution:
  
  
  Adjust Logging Level:
  
  You can reduce the logging level in the ICM settings. This can be done in the SAP GUI by navigating to the transaction code RZ10 (Profile Parameter Maintenance) and adjusting the parameters related to ICM logging.
  Look for parameters like icm/HTTP/logging and set it to a less verbose level.
  
  
  
  Monitor and Analyze Traffic:
  
  Use transaction codes like SM37 to check for long-running jobs or excessive requests that may be causing the high volume of logs.
  Analyze the application or web service that is generating excessive traffic or errors.
  
  
  
  Review Application Code:
  
  If specific applications are causing excessive logging, review the code for any inefficiencies or unnecessary logging statements.
  
  
  
  Increase Log File Size:
  
  If necessary, you can increase the size of the log files to accommodate more entries before suppression occurs. This can also be done in the profile parameters.
  
  
  
  Regular Maintenance:
  
  Implement regular maintenance tasks to clear old log entries and manage log file sizes effectively.
  
  
  
  Related Information:
  
  ICM Configuration: Familiarize yourself with the ICM configuration settings and best practices for logging.
  SAP Notes: Check SAP Notes related to ICM and logging for any specific recommendations or patches that may address known issues.
  Performance Monitoring: Utilize tools like SAP Solution Manager or other monitoring tools to keep an eye on system performance and log generation.
  
  By addressing the underlying causes and adjusting the configuration, you can mitigate the occurrence of the ICM528 error and ensure smoother operation of your SAP system.
