Sorry it took some time, but I did a quick test on my test environment.
I attached a modified vmsd file which now represents the two snapshots on the VM.
You need to upload the file to the datastore. If the two snapshots (Consolidate Helper- 0 and 2) do not show up in the snapshot manager right away, you may need to remove the VM from the inventory (right click the VM in the inventory and select "Remove from Inventory") and add it back again (right click the vmx file in the datastore and select "Add to inventory").
Once you see both snapshots, select the first one "Consolidate Helper- 0" and click "Delete". This will consolidate the 58GB snapshot (...000002.vmdk) into the base disk. This will take some time. Before committing the second snapshot, you should start the VM to see whether the snapshot is still ok after the VM was shut down due to the low disk space. Once the VM starts and everything looks ok, you can delete the second snapshot "Consolidate Helper- 2" in the snapshot manager.
For the above, I assume that your base virtual disk is thick provisioned. If not please report back. Don't try to commit the snapshot in this case!!!
Before you start committing the snapshots, make sure Veeam does not kick in during snapshot consolidation.
