On my Ubuntu production webserver that runs apache/nginx/MySQL and services lots of web customers, it looks like our free Swap memory space is almost all used up. What does this mean? I know that we should add more RAM/memory to the server, but I want to know how bad it will be if current usage continues? We were going to wait until this weekend, when Swap space runs out will the server crash? Grind to a halt? Run really slow?
