Sometimes my multiplayer survival world freezes for a couple seconds (can't mine blocks, mobs freeze but players can still walk around normally), then after the freeze the game jumps back to normal but all players who joined the world get disconnected form it. 

It seems to happen at random times and not very frequently, usually we can play for hours without any issues. Unfortunately I was not able to reproduce it or notice any patterns but it happened at least 4 or 5 times so far in the same world we play in. I haven't seen it happen when playing alone in the world.

Maybe someone here has an idea why this keeps happening?
