My Game keeps freezing on multiplayer

Title: My Game keeps freezing on multiplayer

Version: 3.1.2

OS: Windows 7

Java Version: Java 7

Description of Problem:

When I first log onto a tekkit server everything but after about 5-10 minutes it freezes and I have to shut it down with task manager. When I open it again it does the same thing. I've tried deleting the .technicpack folder and then trying again but it doesn't work. However when I play singleplayer it works fine
