Hello everyone.
The Mixed Reality Forums here are no longer being used or maintained.
There are a few other places we would like to direct you to for support, both from Microsoft and from the community.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.
If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.
And always feel free to hit us up on Twitter @MxdRealityDev.

Does someone already use hololens in sun?
I have used hololens in a open field and at sun (aproximately 30ºC or 86ºF) at middleday.
the hololens restarted twice when it tried to map the space.
does it already happen with someone else?
what may/can cause this problem?
regards.

The HoloLens has very tight heat constraints, so my guess is that the sensors thought the device was overheating. Mapping itself is a highly intensive process that would cause the hardware to heat up, so coupled with a warm day, that would probably trigger a restart.
Via the official documentation "If HoloLens exceeds its thermal capabilities, the foreground application will be shut down to allow the device to cool off"2
