problems with octoprint/prusaprint and camera on zeroW

Hello all together

Ive installed a raspberry zero w and it works very nice with octoprint and prusaprint (both 1.36, i cant see differences..) as long as I dont attach the camera.
When a raspi-camera is installed the system gets very unstable. even with 1 FPS and 640/480 the system hangs within minutes or at least in the first hour. It is not necessary to view the stream with a connected webbrowser. Ive tried several cameras (original 5MP, noname) with several resolutions.... similar results.

Has anyone a zeroW and the rasbicam running successfully?

Once i had got a crash while been connected with ssh running top. Does this gives someone more informations?
