  The SAP error message MSGSERVER008 ("Host name buffer has been reset") typically indicates an issue with the SAP message server's ability to resolve hostnames or maintain a stable connection to the application servers. This can occur due to various reasons, including network issues, configuration problems, or resource limitations.
  Causes:
  
  Network Issues: Problems with the network connection between the message server and application servers can lead to hostname resolution failures.

  Monitor System Resources: Check the system resources on the server running the message server. Ensure that there is enough CPU and memory available. If necessary, optimize the server or consider upgrading resources.
  Update SAP Kernel: If you suspect a bug in the current SAP kernel, consider updating to the latest version or applying relevant patches.
