Python - freesez my Domoticz

[bertbigb]

Dear All,

I have posted a bug in Python probably on the wrong spot.

I'm on a Raspberry Pi 3 Model B+ it runs Raspbian GNU/Linux 10 (buster)
My Domoticz is: Version: 4.11506 - Build Hash: 95e2be251 - Compile Date: 2019-11-21 08:27:50
dzVents Version: 2.5.0 - Python Version: 3.7.3 (default, Apr 3 2019, 05:39:12) [GCC 8.2.0]

My Domoticz freezes and crash within 4 hours of running, the website is then not accessible also anymore.
I hope someone can solve the errors or help me with some guidance how I could solve them myself.

Since I don't want to double post issues I mention here the link to an issue in the Bug and Problem section. It has an example of the few errors I get in the beta release.
It looks afterwards more a Python problem to me. Therfore I paste the link here also.
The link is https://www.domoticz.com/forum/viewtopi ... on#p229081

Some problems I encounter before the system freezes are:
Fatal Python error: Segmentation fault
Error: (Zigate - Zwave) 'onHeartbeat' failed 'KeyError'.
Fatal Python error: Aborted

Please see the link for more detail and I hope someone can help me with resolving the problem.
