For whatever reason, Minecraft on my laptop freezes frequently when trying to pour water or coming in close proximity to horses. Other items, including TNT, do not seem to cause any problems, and most other mobs do not cause any lagging or freezing.

I have tried turning all graphic quality settings to low but nothing seems to work. Setting particles to decreased helped reduce lag and prevented the game from crashing when it started raining, but the game still crashes when I get too close to horses or try to place water.

edit: I couldn't find any folder labeled crash-reports but this is the most recent log I could find. It seems that the server is overloading somehow but I am the only one in it and only horses and water seem to be causing this problem.
