Minecraft Forums

Hey guys!! I've been having a lot of trouble with my Minecraft on all of my computers. Whenever I log in, it works. However, half the times I enter a server or, say, log into a minigame, my Minecraft randomly crashes. It's becoming incredibly frustrating and I have absolutely no idea what to do! I can't put up with it anymore, as it's getting completely out of hand. Any help would be greatly appreciated. Thanks!

I think there are a lot of different ones, but I'll put in the next error log. Thanks for helping!

EDIT: Here it is.

I see you are running optifine, see if the problem happens in vanilla.
