Loosing connection on stop_task action

Hi,
I am loosing my connection to the GVMD when using stop_task on a task, that is not in state “Running”. From what I can tell, it looks like the GVMD is dropping the connection.

    return self._connection.read()

    raise GvmError("Remote closed the connection")
gvm.errors.GvmError: Remote closed the connection

Is that the expected behavior?
I am using:
python 3.7
python-gvm 20.9.1
gvmd 20.08.0

Could you check if gvmd returns an error for <stop_task/>? if yes this behavior is expected. The connection is always closed after an error.

The GVMD log doesn’t show any errors:

event task:MESSAGE:2020-10-20 10h46.26 UTC:6197: Status of task Immediate scan of IP ******* (1d22db1c-7614-4e7c-8721-6ecf51afd029) has changed to Stopped

Python only raises:

gvm.errors.GvmError: Remote closed the connection

I tested this for the states Stopped, Requested and Queued.
During my tests another problem appeared. When stopping a task that is requested, the task appears to be stopped but the ospd-openvas scanner is starting the nvt tests.

Any news on this? I’m facing the same problem.
