Explanation: Another process or a user terminated the tape manager (bptm) or disk manager (bpdm).
Recommended Action: This error should not occur in normal operation. If you want to terminate an active backup, use the NetBackup Activity Monitor.
When you back up a DomainOS client, this error occurs after the server has not received anything on the socket for at least 300 seconds. It causes a client read timeout and breaks the connection. The bpbkar debug log has an entry similar to the following:
13:22:49 [1347] <16> bpbkar: ERR - Extra output - - ECONNRESET Connection reset by peer (UNIX/errno status)
To resolve the problem, increase the CLIENT_READ_TIMEOUT value. In this instance, set the value to 900.
