But without the "CConnection" line in this time...
(version 3.8796)

[micha_pr]

Not sure why,... but I made a second installation now with Stretch and new Python version - now all is stable since more than two hours.
It was not possible before.
At other installation nothing else was installed - it was also a minimal system with Z-Wave-stick only for plugin testing, but Jessie with Python version 3.4.2.
Using Beta 3.8796.

I also have less problems with a complete new install on Stretch. All plugins work great!!! Also the Kodi plugin is better then the standard interface .
I only have sometimes problems with Connections. Last I did 'import urllib.request' and the plugin didn't work. I commented out this line and the plugin was working again. I have to investigate this again, also because something is changed during the last update.

I have seen that any enabled Python Event (the integrated one in Event system with Lua, Blockly...) will cause this error.
Even if enable the sample code the signal 11 error will come up.

It's not easy to go back - because system hang very fast...
Enable sample event:

restarting Domoticz - all is ok, while not python event will be fired:

-> Disable python event, all is ok again...

@micha_pr ,

Can you post the event source that used and if you stored it in a file or the database.

I will try and reproduce it if you do.

I have used for testing the sample code (with setting "All") only-

Thanks!

[Dnpwwo]

@micha_pr,

Thanks. I used the sample as you suggested and could easily get Domoticz to crash quite reliably which was great (kind of ).

Anyway I found an issue in the event system where it was potentially clashing with the Plugin Framework and resolved it. I also found some places where the Plugin Framework was not locking properly either.

I've pushed an update so it will be in the next beta, fingers crossed

[micha_pr]

@Dnpwwo:
In 3.8798 I have still same problem - not sure, your patch is inside?

Thanks!

[Dnpwwo]

@micha_pr,

I assume so but I don't run betas (I build from source).

That said, there are 21 outstanding pull requests so may gizmocuz has taken an Xmas holiday.

Just updated to 3.8799 - at Stretch with Python 3.5.3

Removed the running Python plugin - and created a new integrated Python event - have taken the sample event - not with "All" but in this time with "Device"

Changed a dummy device level - and got again this:

What is your pull request (can not find it in list)?

Maybe your source is different from build - any other/additional files?

Thanks!
