Hi
Over the past several days my HA installation (Raspberry Pi4 : 64 with SSD) has become unstable. It operates fine for 6-7 hours and then some services and integrations stop working, plus random service calls occur.
Initially I thought the problem was my Pi hardware as the issues tended to affect USB connected devices (Z-wave dongle & 2 x RS485). But also connections between HA and Nodered seemed to stop, MQTT had issue etc.
I then noticed that over time my processor loading was increasing and free memory decreasing & once memory got too low the issues seemed to start - which makes sense.
Shortly before the problems started I upgraded to OS8.5, so my suspicions now lie there. However I am not sure of the best way forward & I would appreciate some advice from others in the community. I see two options:-
- Fall back to OS 8.4 or lower & see if the issues are resolved
- Retain OS8.5 & delete integrations one at a time to see if I can find one that is the cause of the issues.
Option 1 appeals, but I am not 100% sure of how to do this. I think all I need to do is reflash the SSD with OS 8.4 & then restore my configuration from backups (I have a full backup from a couple of days prior to the issues arising - any yes I have already tried to just restore the backup but it made no difference). Is it that simple? The issue I see with this option is that at some stage in the future I will still need to upgrade the OS & the issues may arise again, so maybe better to find the root cause?
Option 2 will take more trial and error and potentially could end up with my having to stop using an integration until it becomes compatible with OS8.5.
Any thoughts/advice from the community much appreciated. Note I am good at following instructions, but my ability to understand code is very limited.
