What is all this memory used for?
In Virtualmin I got an overview of my running processes. I thought my 2GB server was more than enough - for application I use 512M is the recommended minimum. But when I see the statistics much of those 2GB is used. What is happening? Why is Digital Ocean consuming so much itself?
