[ovirt-users] Failing vm backup

Hi, since yesterday backup for one of my VMs is failing. Backup is performed by Storware vprotect, based on CBT strategy. In ovirt events I can see: VDSM host03 command StartNbdServerVDS failed: Bitmap does not exist: "{'reason': 'Bitmap does not exist in /rhev/data-center/mnt/blockSD/459011cf-ebb6-46ff-831d-8ccfafd82c8a/images/a9ec8085-6ac3-4be0-bbd2-7752f7e29368/083f5dc5-9003-4908-96b1-5f750b5a4197', 'bitmap': '1b88a937-0ab8-4f6e-a117-bbd522e21448'}" Transfer was stopped by system. Reason: failed to create a signed image ticket. Backups for other VMs are working correctly. What could it be? Somehow corrupted image? I tried to migrate VM to other hypervisors, with no luck. Didn't tried to move disks (two, one for the OS, one for data) to another data domain, not so fast operation (about 2.8TB). The VM is working correctly, but Murphy's law states this machine is a fileserver with users' data and email :-( Any hint?
