The vCenter Server must terminate vSphere Client sessions after 15 minutes of inactivity.

Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free resources committed by the managed network element.
