  The SAP error message ICM605 indicates that the number of cache entries in the Internet Communication Manager (ICM) has exceeded a predefined threshold value. This can lead to performance issues or even service disruptions if not addressed.
  Cause:
  The error typically arises due to one or more of the following reasons:
  
  High Traffic Volume: An increase in the number of requests being processed by the ICM can lead to a rapid accumulation of cache entries.

  Inefficient Cache Management: If the cache is not being cleared or managed properly, it can fill up quickly.
  Application Behavior: Certain applications may generate a large number of cache entries due to their design or usage patterns.
  
  Solution:
  To resolve the ICM605 error, consider the following steps:
  
  
  Increase Cache Size:
