Often happen that the grid server close all the connection and I cannot connect to the server machine either via RDP.
This is a short video showing the current situation:

The only way to solve this is to manually switch off the physical server machine and restart it.
As far as I can see, sometimes the machine where the grid server is installed reaches a status of saturation for which all the connections are closed.
How can I avoid this?
