Minecraft freezing time?

[3.1459]

So lately minecraft has been freezing and by freezing I mean animals and blocks ar frozen whether i hit or break them i does nothing and the next chunk wont load i've used task manager to force-close the game because if i try to save and exit it freezes at the save page and it not just one world every time I reload the same world things start moving again but for only about 2 seconds before it freezes and there isn't a crash report because the game doesn't crash everything just stops moving ive been trying to figure out what has been causing this but i not sure where to look to figure out the problem 

here is the debug log
