Camera stream freezing

[Anacardium]

Hi!

My V0.2 is running fine. Printing is all good and now even better using the new improved Mini Stealthburner with Orbiter 2.0.

But: When ever I´m watching the camera feed of my Raspberry 2 cam, ping times increase and the video starts to freeze. Finally, the printer is not reachable any more.

Ping without watching camera stream:

Ping when watching the stream:

Often it results in loosing the connection.

I already implemented a script as cron job which is checking ping time and resetting the connection if time goes over 50ms. But that´s only a bad work around, no real solution, of course.

My crownsnest config looks like:

----------------------------

log_level: verbose                      # Valid Options are quiet/verbose/debug

enable_rtsp: false                      # If camera-streamer is used, this enables also usage of an rtsp server

#custom_flags:                          # You can run the Stream Services with custom flags.
#v4l2ctl:                               # Add v4l2-ctl parameters to setup your camera, see Log what your cam is capable of.

----------------------------

Behavior is not as bad when using 640x480 and lower fps like 15. It takes longer to show the issue, but it is still there.

I´m running out of ideas. 

Any suggestion what I could check or change is highly appreciated.
