My server is running on CentOS 7, and the RAM usage is always maxed out. I had 1 GB, and it was maxed, now I upgraded to 2 GB and it is maxed out.
I am not sure what services need most RAM
There is one systemd-journal, uses a lot of ram, and several instances of apache
Is there anything I could do - some settings, to optimize and maybe lower RAM usage?
