Occasionally high memory usage

[nazar-pc]

Describe the issue you are experiencing

I believe this is the third time this happened to me. Home Assistant is usually running fine for days with stable memory usage and then suddenly memory usage is growing significantly. Once it hanged the whole thing, two more times (including today) just resulted in high memory usage and monitoring alerts:

I looked inside and python3 -m homeassistant --config /config is the process that is currently using 56.6% of RAM (on VM with just 2G of RAM).

Memory usage started to recover for some reason, have not done anything to cause that :man_shrugging: Home Assistant is not reachable from public Internet.

There is no records in Home Assistant Core logs. Supervisor logs have this, looks like it restarted today, though no idea why it would do that (doesn't correlate with the memory usage increase either):

If the offending process is python3 -m homeassistant --config /config, it means the issue lies in the Home Assistant Core, there's very likely no relation with the underlying OS. To get proper support, if the issue appears again, report it in the Core repository. In the meantime, you might want to have a look at the profiler integration and/or a bdraco's post about integration troubleshooting.
