Hello everyone.

Is someone ever saw 'endless snapshot' problem? Some instances (with raw 
disks and live snapshoting enabled) are stuck at image_uploading forever.

It looks like this:

...etc

Any ideas why this happens? All logs are clear, no errors or anything. 
And it happens at random so no 'debug' log available...
