MaxDB 7.8 backup problem

Hi guys,

        I'm facing problems with a MaxDB database 7.8 (7.8.02.21) 32 bits, installed in a Windows 2003 Server 32 Bits.

        The database has 1Tb and it was running fine until January/2015.

        There was a Microsoft Windows Security Patch applied in this server and, maybe by coincidence, the Database Backup COMPLETE and the Database Backup INCREMENTAL don't run anymore and return the error below:

              -915 No more memory 3,Data backup failed

        After this process the database status has changed to OFFLINE.

        Do you know a way to solve this problema?

Thanks in advance!
