Explanation: vmd cannot send the status of a requested operation to the requestor. (vmd is the NetBackup Volume Manager daemon on UNIX and Linux and the NetBackup Volume Manager service on Windows.)
Examine the daemon debug log for a more detailed message on the system error. Examine command output, debug logs, and system logs for a more detailed message on the error.
Obtain the specific send or write system call failure from the debug log, and investigate the operating system functionality that is related to the failure.
Use the following steps to check whether the command or the application interface that sends the request aborts prematurely: enable reqlib debug logs, retry the operation, check the debug logs, and observe application interface output.
The server encountered an internal error or misconfiguration and was unable to complete your request.
