Why are ANR8216W messages logged into the activity log for the backup of Tivoli Storage Manager for Enterprise Resource Planning even without any backup failure?
This may occur if a number of sessions gets created according to the values specified in the profile, but not all of these sessions will be used to retrieve logs that have already been stored on the Tivoli Storage Manager server. Only those sessions that have been used are closed correctly. All other sessions that have not been used are (just) destroyed. This causes the ANR8216W messages in the activity log.
The server experienced a TCP/IP error while sending data on socket socket number. Reason return code.
A communication error occurred on the indicated socket. This may be a normal event if either side of the connection is abruptly ended.
The session is ended. Server operation continues.
If the session is ended as a result of intentionally stopping either the client or server, no action is required. Otherwise, ensure that the client and server can communicate using Telnet or FTP applications, which are part of the TCP/IP suite.
These errors in the Tivoli Storage Manager server activity log may be ignored and there is no need to investigate them further.
