NetBackup status code: 143

Message: invalid command protocol

Explanation: A poorly formed request was made to the NetBackup Request Daemon (UNIX) or to the Request Manager service (Windows). This error can be due to the following: mismatched versions of the product, corrupted network communication, or to a non-NetBackup process sending data across the port for the daemon or service.

Recommended Action: Examine the NetBackup error logs to determine the system that was the source of the data. On that system, determine the process that initiated the request. If it was a NetBackup process, verify that the process or command is compatible with the version of software on the server.
