Are you sure you don’t have other processes or users running on the system? It only happens when you have a network connection? It might also be swapping heavily, check to see how much RAM you have. Check the output of ‘free’. Look at the syslogs/journal when you’re logged in (in a terminal, run ’sudo journalctl -xfl’). You will see a lot of stuff printed, but it might give you an idea of what’s going on. -- Jonathan Billings <billings at negate.org>
