Servo jitter on enter/wakeup sleep


I let my spark core go into deep sleep mode. What troubles me is that whenever he enters the mode or wakes up from it, the server moves slightly or repositions imself. How can I circumvent this? I tried to pull the PWM Line high, so on power down PWM is not flapping in the breeze but has a solid state. But this did not worked out. What can I do?
