Symptoms

VProtect from StorWare has several methods to perform VM backups in OLVM.
One of those methods consists of taking a snapshot of the VM disks, then downloading the snapshot disks through the Python SDK.

When downloading the snapshot disk, the download fails and the disk becomes in a Locked Status.
In engine.log the following error is reported:
