Minecraft Forums

I play on my FTB ulimited server(added Ars Magica) and after updating my client, every few minutes of playing would close my game. I have uninstalled and reinstalled java several times, and have also re-downloaded FTB entirely. I sometimes get a ran out of memory error, and sometimes get a sound error. I play without sound and have 4 gigs dedicated to minecraft(out of 8). My game worked fine before and ever since I have been unable to play for more than 7 - 15 minutes without it crashing.
