• What is the cause and solution for SAP error message SCLNT_HTTP404 - ICM memory request failed (ICM_HTTP_NO_MORE_MEMORY) ?

  The SAP error message SCLNT_HTTP404 ICM memory request failed (ICM_HTTP_NO_MORE_MEMORY) indicates that the Internet Communication Manager (ICM) in the SAP system has run out of memory to handle HTTP requests. This can occur due to various reasons, such as high traffic, memory leaks, or insufficient memory allocation for the ICM.
  Causes:
  
  High Traffic: A sudden spike in the number of HTTP requests can exhaust the available memory.
  Memory Leaks: Inefficient handling of memory in the application or in the ICM itself can lead to memory not being released properly.
  
  Configuration Issues: The ICM may not be configured with sufficient memory limits to handle the expected load.
  Resource Limits: Operating system-level limits on memory usage can also contribute to this issue.
  
  Solutions:
  
  
  Increase Memory Allocation:
  
  Adjust the ICM memory settings in the SAP profile parameters. You can increase the icm/HTTP/max_request_size and icm/HTTP/number_of_requests parameters to allow for more concurrent requests and larger request sizes.
  Example parameters to check:
  icm/HTTP/number_of_requests
  icm/HTTP/max_request_size
