Camera on Voxl2 (hires-front-small-encoded) breaking after 6-8 minutes running

[Adnaan Yunus]

Hi,

I have a voxl 2 starling drone and I am running the camera stream using hireses_front_small_encoded inside adb shell via voxl-camera-server -d 0. Its crashing after 5-7 minutes, not sure what it is wanted to send here for inquiry purposes.
