Issues with RAM memory?

Hi all,

I have an issue with my Home Assistant (HAOS in Raspberry), I would like to please ask for opinion/ideas…

Since several weeks ago, after 4 o5 days running my HA is KO, apparently free RAM memory starts to reduce until almost 0 (I have 2GB). Any idea about how to fix this? Could be a problem of memory or addon? I haven’t installed new addons or something, just updating. Any way to check if RAM itself is damaged?

Thank you!!!
