Here is more detail to my process and set up.
FCPX is installed on my iMac 27 (Late 2013).
3.5 GHz Intel Core i7
32GB 1600Mhz DDR3
NVIDA GeForce GTX 780M 4096MB
All FCPX video data and files/folders stored on external 9TB RAID-5.
From day 1 I have SHARED (rendered) my FCPX MP4 (Fast) and MOV files to my Mac Drive. This has worked fine until yesterday. That is when FCPX started shutting down sometime during the SHARE process. I’ve SHARED 2 renderings (1 MP4-Fast and 1 MOV) to my RAID and they completed the process.
So it is looking like something has gone a bit “south” on my Mac Drive.
