Lag/crash. Pigs infinatly spawn and dissapear afterwards. Minecraft crashes when i log into the world with pigs but sometimes works. This is on singleplayer.

This is true on Minecraft Servers in 1.4.5 Since, it has been fixed. Is this Single Player, Multiplayer or LAN?

Please attach the crash report.

Here's the crash report
