Default high memory usage

I have been using ispconfig 3 for quite a while now. Recently, something is not right. Memory usage is hitting up the roof. So I upgraded from 2GB to 8GB yesterday.

This morning when I check the system, I see all the 8GB used up. I feel something is not right. There might be some rogue processes running inside.

I used top to see the memory usage but I can't see anything. Anyone can guide me on checking what is using up all the memory? The "show memory" in ISPconfig is not showing anything useful that I can used.

Here is the top result sorted by memory:
Code:
top - 11:16:17 up 17:52,  2 users,  load average: 0.06, 0.19, 0.17
