 My server has 40G memory, which actually takes up 34g. But sometimes I will prompt this error.
I host my own server (no server provider) and i have around 55 plugins and my server takes around 10gb ram. I have noticed some hoster providers say they give 64gb ram but when we checked it’s actually 8gb ram. So check with your provider
