- Hardware: Celeron N3060(2x 1,6Ghz) / 4GB / 120GB SSD

openHAB version: 2.4.0
Issue of the topic:
I have encountered that the camera stream is lagging on my sitemap, but it wasn’t since I set it up.
So I found out that CPU is on 100% when OH2 Server is running, that exact OH2 version ran on this PC for almost a year with 60% load max (except on startup it was 90% but that was normal).
In ttop I’ve found 4 tasks named qtp464142861 that had 1 hour or higher CPU time. Probably those are malfunctioning but I don’t know what are they. As they have so non-descriptive names that Google found nothing.
They are acting wierd, and not always up after a restart, so hard to trace.
I 've included some logs in the attached file. If anyone can point out which logs would tell more info, that would be nice.
Right now the system is usable with 60% CPU but daily it happens to go to 100% and stays there until i restart Openhab. So not sure if any of my rules are problematic but I doubt as I changed them on 18th August, and things on 15th October nothing later. (As i’ve read about high cpu at parsing rules)
CPU In task manager (aprox.) :
- 7% vlc rtsp stream
- 50% java (openhab)
- 1% UniFi Controller
- 2% Others
I am having no trouble with OH 2.4 on raspberry at Weekend House,
and I know some linux as well, Is the anwser repair the system or go to Linux, copy conf and write mqtt things in Studio instead of Paper UI (as i don’t know how to transfer them from Paper UI on this OH to another system, now it is also hard to backup .things as backup.bat throws an error).
[On raspberry i have also .things in conf and it is nice to bakup.]
If anwser is linux, I have no idea which distro to use to be light-weight maybe pepermint as I had problems with installing debian on some other PC…any better distro (with desktop for using on kitchen TV ocasionally).
Thanks in advance
