This only happens with Lightroom CC 2015. Nikon View NX exports hundreds of files successfully.

The whole system shuts down, or just Lightroom crashes?

Hi Chris... The shutdown continues to occur and I need an answer soon. Again the problem surfaced when I installed Lightroom CC 2015. Lightroom 5 worked just fine.

I look forward to your reply.

Lightroom 6 / CC now automatically parallelizes exports into multiple smaller exports (Lightroom 5 did not do that). Because of the parallel threads, a typical CPU (Intel i7) is working at full capacity during export, with all virtual cores (e.g. 8x) at nearly 100% load.

Like any other CPU-intensive multithreaded program, this will tremendously increase the temperature of the CPU. There are some cases where the CPU heat sink and cooling fan are defective or not properly installed. The CPU then overheats and will shutdown to protect itself from thermal overload.

It would be advisable to get your PC/Notebook checked by a computer technician. Addittionally, you should look into the windows event log and look for an error entry like "The previous shutdown was due to Thermal Event" at the time of the reboot. If such entries are present, there is definitely something wrong with your CPU's cooling.

At your own risk, you also could try a "CPU burn-in tool" to check the thermal stability of your computer - with the possible risk of damaging the CPU and/or other parts.
