Please follow the instructions at https://community.home-assistant.io/t/2024-5-tracking-down-instability-issues-caused-by-integrations/724441 and post a callgrind file

jymorel commented 1 week ago

so I have installed again version 2024.5.1yesterday evening at about 9:00pm. You will find attached the history of CPU and memory usage. And a callgrind file. Thank you HAOS_2024 5 1_2024-05-06 callgrind.out.1715013163860053.txt

Looks like a run-away template

Please follow the instructions at https://community.home-assistant.io/t/2024-5-tracking-down-instability-issues-caused-by-integrations/724441 to identify it

Idid that and I looked at the log. I found 2 templates used in sensors for getting lists of last seen devices and unavailable devices with more than 100000 renders ... But strangely, cpu and memory usage decreased significantly and returned to normal after installing 2024.5.2...? Seems to be stable now. HA 2024 5 2_installation

fixed by HA 2024 5 2 before and after upgrade to 2024.5.2.

bdraco commented 1 week ago

I'm not 100% sure that this problem is fixed, as there wasn't anything specifically for templates in 2024.5.2. Perhaps it was the statistics fix? Do you use the statistics integration?

If you send another callgrind file. I'll also take a look and see if there's anything obvious going on that might cause the problem to reoccur.

jymorel commented 1 week ago

No I don’t use the statistics integration. Only 1 history_stats sensor for testing. Ok attached a new callgrind file. FYI, not a best practise for testing, but I installed go2rtc and alexa media player updates at the same time as HA 2024.5.2 update … callgrind.out.1715104561015525.txt
