Question : removing old snapshots created when virtual disks where in Independant non-persistent mode

I have a VM that reboots whenever I try to create a snapshot.  It started when the VM had disks in Independant Non-persistent mode.  This was enabled by accident.  Since then I've changed the drives to Normal mode, however, whenever I try to create a snapshot using VEEAM or any other 3rd party backup application the snapshot creation fails and then the VM reboots.  VEEAM tech support says I need to call VMWare and have them consolidate these snapshots.  Does anyone has any other suggestions?

What is your backup target? Can you configure your backup to use vStorage API Network (NBD) mode and see if that helps?
