• What is the cause and solution for SAP error message /IWXBE/CORE135 - Error while getting channel instance or initialization of MQTT or Daemon ?

  The SAP error message /IWXBE/CORE135 typically indicates an issue related to the initialization of the MQTT (Message Queuing Telemetry Transport) channel or daemon in the SAP system. This error can arise due to various reasons, including configuration issues, network problems, or resource limitations.
  Causes:
  
  Configuration Issues: Incorrect settings in the MQTT configuration can lead to initialization failures. This includes wrong broker addresses, ports, or authentication credentials.
  Network Problems: If the SAP system cannot reach the MQTT broker due to network issues (firewall settings, DNS resolution problems, etc.), it may result in this error.
  Resource Limitations: Insufficient system resources (CPU, memory) on the server where the SAP system is running can prevent the MQTT daemon from starting properly.
  MQTT Broker Issues: The MQTT broker itself may be down or misconfigured, leading to connection failures.
  Version Compatibility: Incompatibility between the SAP system version and the MQTT broker version can also cause issues.
  
  Solutions:
  
  Check Configuration: Review the MQTT configuration settings in the SAP system. Ensure that the broker address, port, and authentication details are correct.
  Network Connectivity: Test the network connection to the MQTT broker. Use tools like ping or telnet to verify connectivity to the broker's IP and port.
  Resource Monitoring: Monitor the system resources on the server. Ensure that there is enough CPU and memory available for the SAP system and the MQTT daemon.
  Broker Status: Check the status of the MQTT broker. Ensure that it is running and properly configured to accept connections from the SAP system.
  Logs and Traces: Review the logs and traces in the SAP system for more detailed error messages that can provide additional context about the failure.
  Update Software: Ensure that both the SAP system and the MQTT broker are updated to compatible versions. Check for any patches or updates that may address known issues.
  Restart Services: Sometimes, simply restarting the MQTT daemon or the entire SAP system can resolve transient issues.
