Nobody any idea???
The error comes from this line:

Code: Select all

Plugins::CPluginSystem::StopPluginSystem()

Why does this StopPluginSystem gives an error?
It is that last part of the stopping of Domoticz.

In the Python doc is this remark present

Code: Select all

Note Calling this function from a thread when the runtime is finalizing will hang the thread until the program exits,
even if the thread was not created by Python. Refer to Cautions regarding runtime finalization for more details.

Could this have anything to do with the abnormal exit of Domoticz?

As I remember it could be related to python modules that are used by Python plugins that have memory release issues.
Check GitHub issues on this issue.

[Kedi]

Tnx, I will try to check that and my plugins.

With build 17189 this error has gone.

Strange yesterday we were at build 17189, and today we are at 17163.
Is the counter going backwards?
B.t.w. Problem is still gone.

Gizmocuz had to revert some unwanted changes (due to Copilot assistance). He is working on it.
