make sure you dont have records at async_tasks with vdsm_task_id of
"empty guid" - but i'm really not in favor of such hacks, this is a
hack. I strongly suggest you solve upgrade issue (please communicate
with ofer on this).
OK, I understand that, but for the record: 'async_tasks' was completely
empty before I started Engine, so this hack wouldn't have been of any use.
