I've found something like this when TSM is reopening the sessions and the Backup take longer than the duration specified in the scheduler. It's followed by the message ANR2576W (in the Server LOG) when the Backup really ends. I'm using TSm 3.7.3 on OS/390 2.7 and the client is ADSM 3.1.0.8 (so there's no controlling session). I hope this helps Ramon Colet Aigües de Barcelona
