Lag then crash

[Alfff]

On a friends server, the game slows to a complete crawl and when I relog it crashes. Any help to solve this would be appreciated. Here's the error report.

java.lang.OutOfMemoryError

Assign more RAM to your game/server and increase permgen. If it's your client that's crashing, click the gear on top of the launcher. For a server, your launcher script should look like this:

java -Xmx4G -Xms2G -XX:MaxPermSize=256M -jar Hexxit.jar nogui

You should assign at least 350 MB to it, or if you are using a shader/HD texture pack, assign closer to a GB.
