TSM for Sharepoint full granular backup hang after 18%

[tsmfreak]

we have 2 farms :

1) Prod : WFE , AS ,Search , SQL , DocAve (TSM4MOSS 6.1.4) Media + Manager on Windows Server 2003

62GB completes with little exceptions (Error message: Please help to check if there's any lists with illegl characters in its name under teh web) but ends
between 6 and 9 hours !!!



2) Future Prod (=copy of 1) : WFE, AS, Search SQL , DocAve (TSM4MOSS 6.1.4) Media + Manager on Windows Server 2008

hang after 18% !!!



after 18% backup there is no more data transfer and after 1 hour idle time the TSM session is terminated.

In the TSM Table backups there are no new TSM objects (50MB chunks) created.

On the media server in the AvePoint-ZeusMedia.log I can see the following entries :
