Domoticz crashes with fatal signal 6 (Aborted) when running SVT

[WiktorBuczko]

My Domoticz (Stable 4.10717) is running on Raspberry Pi Zero W (Raspbian Buster). Every 1-2 hours it crashes

I have three instances of Smart Virtual Thermostat running. When I disable the heating in all thermostats then Domoticz does not crash. Setting the logging level of SVT to debug does not give anything useful in log. What could be the problem?

Hi. This log does not contain any message from the plugin itself but rather with the plugin framework... So hard to debug !

1. Did you enable debug logging both in domoticz and in the plugin ?

2. I understand that when the thermostat is off, there is no crash, but the temperature readings are ok ?

3. May be it is the switching on/off of the heating device that fails ? I assume if you manually switch the heating device(s) there is no issue ?
