Logged Error OC 1.5.9

I found this in the middle of my log file.  I think this occurred during a autosave due to pauseing, note that the error timestamp is one minute after that.  The error did not repeat anywhere, and did not make any report visible from the game.  I was trying to turn on my microcontroller (I made several attempts).  The microcontroller is supposed to emit redstone signals and it is not doing that.  The analyzer isn't reporting any errors either.
