I have checked your site and all looks god, vps parameters all look good too.
edit: I can see in logs you got to 90% of memory, that may have been the cause, it looks like IIS was reset or the reboot worked and it is back in operation.
Well… the site is up and running fine but in Viruozzo I still can’t restart the VPS (it says - VPS is running at the moment. To process requested operation VPS should have state .) or see the resources used. (it says n/a)
Very odd, are you at a point you can submit a ticket now? Our info to login was not working so I was unable to see it as you, it was working properly to display as admin of the server.
