Explanation: The bpsynth process cannot send the exit message to indicate the end of extents messages to the following: bptm or the bpdm reader process on the media server. The network connection between the master and the media server may have terminated or the bptm or the bpdm reader process has terminated.
Recommended Action: Check the network connectivity between the master and the media server. Examine the NetBackup error log for any errors that bpsynth and bptm or the bpdm reader process logged. Examine the debug logs for bpsynth on the master server and bptm or the bpdm reader process on the media servers for more detailed information. If the problem persists, contact customer support and provide the appropriate logs.
