I updated my server to 1.6.1 and thought i would be able to just play.

what happens is at random times my game just stops,not crashes, but stops and tells me it could be that i don't have enough allocated memory but i have enough memory. And it gives me the option to go back to the title screen or quit but no matter what it closes minecraft on me. im pretty sure its my minecraft not the server, no one else on it got this.

Steps to Reproduce:
1. Go on my/any server with 1.6.1
2. play for a little bit
3. eventually it will do that
