  The SAP error message /OSP/A_MSG164 ICM check failed: ICM is not running indicates that the Internet Communication Manager (ICM) is not running in your SAP system. The ICM is responsible for handling HTTP(S) requests and is crucial for web-based applications and services in SAP.
  Causes:
  
  ICM Not Started: The ICM process may not have been started, either due to a system restart or manual intervention.
  Configuration Issues: There may be misconfigurations in the ICM settings in the SAP profile or instance configuration.
  Resource Limitations: The system may be running out of resources (memory, CPU) that prevent the ICM from starting.
  Errors in Logs: There may be underlying issues indicated in the ICM logs that prevent it from running properly.
  Network Issues: Network configurations or firewall settings may be blocking the ICM from starting or accepting connections.
  
  Solutions:
  
  
  Start the ICM:
  
  You can start the ICM using the SAP Management Console (SAP MMC) or by executing the following command in the command line:
  startsap ICM
  
  Alternatively, you can restart the entire SAP instance, which will also start the ICM.
  
  
  
  Check ICM Configuration:
  
  Review the instance profile parameters related to ICM (e.g., icm/server_port_0, icm/HTTP/port, etc.) to ensure they are correctly configured.
  Use transaction RZ10 to check and modify the profile parameters if necessary.
  
  
  
  Review Logs:
  
  Check the ICM logs for any error messages that might indicate why it is not starting. You can find the logs in the directory specified by the DIR_LOG parameter in the instance profile.

  Check System Resources:

  Use tools like top, htop, or Windows Task Manager to check resource usage.
  
  
  
  Network Configuration:
  
  Ensure that the network settings are correct and that there are no firewall rules blocking the ICM ports.
  Verify that the hostname and IP address configurations are correct.
