NW60-SP5, all current patches
BackupExec 9.1 incl. OFM, latest build

BE backs up 3 servers including the media-server, all with
ofm. The backup runs fine, even on the remote servers, only
on the media-server while backing up the SYS-volume there
are several system-files reported as being open during
backup. Since te backup-log also states, that SYS is backed
up using OFM, I think there is something running wrong.

Has anybody with BE-experience run into something similiar
and an idea on how to overcome this problem?
