Hello,

The user does not receive confirmation of the operation.
>From the point of view of user input it looks like the machine itself
stopped.

As you can see in the logs, the ACS explicitly sends stop command, as if
they press the Stop button from the GUI, so it is aware of the action from
the perspective of the ACS / MS.

I can not point out which component may be responsible for it.
We have tried to analyze the code to understand what is happening,
but the part of the code related to HAWorker is not very clear.
Unfortunately we could not find online any assumptions on the level of
architecture / design of HAWorker.
Maybe method of small steps help find a solution.
First a small question: why HAWorker performs reschedule. What was the idea
for such action.
