Error description
Scheduled backup operations may be missed after a backup fails due to a failure to re-establish a session terminated by the server for having exceeded the IDLETIMEOUT value earlier in the backup process. The following error will be seen in the schedule log: ANS1369E Session Rejected: The session was canceled by the server administrator. Customer/L2 Diagnostics: No issues are seen with the backup until a session needs to be re-established due to the session having been terminated due to idletimeout. The server actlog will show that a session is terminated for the node: 01/12/2015 22:00:02 ANR0482W Session 66152 for node NODE1 (WinNT) terminated - idle for more than 60 minutes. (SESSION: 66152) Actlog later simply shows a session begin, then end: 01/12/2015 22:18:44 ANR0406I Session 66851 started for node NODE1 (WinNT) (Tcp/Ip x.x.x.x(xxxxx)). 01/12/2015 22:18:44 ANR0403I Session 66851 ended for node NODE1 (WinNT). The client trace shows a failure to re-establish a session, then later shows a session successfully established.

The failure leaves the scheduler in a state where subsequent scheduled backups are missed. Tivoli Storage Manager Versions Affected: 6.3, 6.3, 6.4, 7.1
Local fix
The problem may be avoided by setting the idletimeout server option value high enough that it is not exceeded by client sessions. The client services may be halted and restarted to clear the hang if it occurs.
