I have an Ubuntu 16.04 server with ISPConfig Version: 3.1dev. and many websites installed. I know I have to update my system, but for some reason the server starts working too much on some processes with high load and it gets too slow from time to time. I don't know what the running processes associated with this problem are, but it doesn't work well anymore. I tried using the top command to identify the running processes, but there are too many and it's not clear where the problem is. Hopefully someone can shed some light.
