Game crashed out of nowhere

For some reason, while playing in a casual smp server with my friends, my game just crashed. Now this isnt the first time my games crashes due to dh (you can see its dh from the logs), but ill usually ignore it as just a simple restart fixes everything. This is like the 10th and it have gotten into my nerves.

Game in it self have no reason to crash as I have really good pc specs..
