Yes, you did nothing... You just restarted those 3 servers on Hyper-V without changing anything... And you did not change the Settings of 2 Windows Server to a static amount of Ram. And you also did not change the settings of the Unix Server to dynamic amount of Ram. And this has absolute nothing to do with the constantly crashing apps on the unix server sience then, because he does not support Dynamic Memory.
Fuck all those people who claim that they did nothing, even though it's obvious.
