Every Now and Then

OK, well I shouldn’t be complaining because everything has been running like a well oiled machine for quite a long time however, every now and then I get this message every time someone goes to watch something that there ain’t enough processing power to transcode the file. After that I pretty much have to reboot. I have checked everything 3 times and all is well. It’s not a deficiency on my end because I am over the top on CPU, memory and SSD-HDD space. 12 logical cores core i7 4.2, 32GB RAM, and about 100TB of space, no problem there. Can’t seem to figure it out, any suggestions??
