(4.10.1)Texture streaming error on IOS

Here’s the package log:[link text][1]
Also I found this line in the device log:
LogMetal:Display: Loaded a non-offline compiled shader (will be slower to load)
I think this is the reason why my game just gets stuck for a moment from time to time.Could you help me solve this?Thanks a lot.
