Has anyone encountered the same issue that 4k High-resolution Image Sensor running on VOXL2 stops publishing frames after a minute or so?  The issue is exacerbated under temperatures exceeding 90 F.  The issue can be mitigated under lower fps.   Seems like a heat and/memory leak issue.  Any advice would be greatly appreciated.

The kernel will start shutting off processes at 90 F

What version of software are you using, and how are you streaming the images? If you use SDK 1.0 and the h265 interface, 4k should be minimal thermal impact

@Chad-Sweet @Wei-Cui-0 
Did you mean to write 90-C Chad in your response?

@Wei-Cui-0 I am facing similar issue with tracking camera where my CPU temperature was raising above 95 degrees and voxl-camera-server is shutting down which leads to crash while operating flight in VIO mode.
@Chad-Sweet Can you please confirm this?

@Chad-Sweet Thanks Chad.  We have SDK 0.8 onboard.  We are not streaming videos. The issue occurs more frequently in the field, where the temperature exceeds 90 F in the summer.
