Communication between Asyncio DS and client DeviceProxy times out, when DS is observed by Jive ATK panel

Dear all, I have a simple pyTango DS in asyncio mode that only provides two scalar double attributes.

class LVProxyAsync(Device):
    green_mode = GreenMode.Asyncio

    async def init_device(self):
        super().init_device()
        self._sinus_signal=float('nan')
        self._saw_signal = float('nan')
        self.set_change_event('sinus_signal', True, False)
        self.set_change_event('saw_signal', True, False)
        self.set_state(DevState.RUNNING)

    @attribute(dtype=float)
    async def sinus_signal(self):
        return self._sinus_signal

    @sinus_signal.write
    async def set_sinus_signal(self, nValue):
        self.debug_stream(f"Write Sinus: {nValue}")
        self._sinus_signal = nValue
        self.push_change_event("sinus_signal", nValue, time.time() , q.ATTR_VALID)

    @attribute(dtype=float)
    async def saw_signal(self):
        return self._saw_signal

    @saw_signal.write
    async def set_saw_signal(self, nValue):
        self._saw_signal=nValue
        self.push_change_event("saw_signal", nValue, time.time() , q.ATTR_VALID)

I write the attributes in a test client

from tango.asyncio import DeviceProxy as aDS
import numpy, asyncio, tango

i = 0
lvproxy_async = await aDS("lvproxyasync/lvproxyasync/1")
while True:
    await lvproxy_async.write_attribute("sinus_signal", numpy.sin(i))
    await lvproxy_async.write_attribute("saw_signal", numpy.sin(i))
    await asyncio.sleep(0.1)
    i += 1

When the Jive ATK panel is open for the DS the communication crashes after some writes with the error:

CommunicationFailed                       Traceback (most recent call last)
Cell In[6], line 8
      5 lvproxy_async = await aDS("lvproxyasync/lvproxyasync/1")
      6 while True:
      7     # try:
----> 8     await lvproxy_async.write_attribute("sinus_signal", numpy.sin(i))
      9     await lvproxy_async.write_attribute("saw_signal", numpy.sin(i))
     10     await asyncio.sleep(0.1)

     55     return
     57 try:

     59 except BaseException as exc:
     60     self.future.set_exception(exc)

CommunicationFailed: DevFailed[
DevError[
    desc = TRANSIENT CORBA system exception: TRANSIENT_CallTimedout
  origin = DeviceProxy:write_attribute()
  reason = API_CorbaException
severity = ERR]

DevError[
    desc = Timeout (3000 mS) exceeded on device lvproxyasync/lvproxyasync/1
  origin = DeviceProxy:write_attribute()
  reason = API_DeviceTimedOut
severity = ERR]
]

Various scenarios were tested: Tango DB running on Ubuntu 22.04 VM hosted on a Windows 10 PC

1. DS and test code on Windows 10 host
2. DS on VM, test code on Windows 10
3. both on VM

Allways with same result.

It seems to be a general problem affects every asyncio DS.
