WaitableTimer slept too long/short

I get a lot of warnings in my simple OpenSceneGraph (OpenGL) application running with the latest SDK 1.20.0:
...
06/12 17:25:32.939 {!ERROR!} [Kernel:Default] WaitableTimer slept too long/short (i.e. 1.738477 ms)
06/12 17:25:41.174 {!ERROR!} [Kernel:Default] WaitableTimer slept too long/short (i.e. 2.374699 ms)
...
I have tried to replicate the behavior of the OculusRoomTiny(GL) demo, but I am obviously missing something, since the demo runs without these warnings.
What is the source of these warnings?

    Regretfully my Oculus device broke short after writing this question and I am currently in talks with the support people regarding an RMA.

    But I was mostly interested in what part of the Oculus SDK these warnings had their origin from.
    What is it this warning is trying to tell me?

    I have attached the logs as requested.

    This was the latest output in visual studio 2017 when I ran my test:
