Hmmm, I haven't upgraded to the 4.0.1.2 yet. But, today I added 3 more hard drives to my bvr. To make all 3 fit in the case with the other 2. I had to do some customizing on the case. Needless to say she was stripped down for hours! I got the customizing done, cleaned everything real good, and reformatted all the drives. Now, here's the kicker! The cpu usage is back to normal with blue iris! I wonder if having it off (unplugged) cleared something in the memory related to bi. Hmmm, i'm happy! Just not sure what really fixed the high cpu usage. If I was betting though, I would bet the unplugging of my bvr for so long cleared it up!
