Random stopping issue?

[Rubri]

Having an issue with playing mindcrack pack suddenly. The only thing that the console log say sis "STOPPING! SOUND SYSTEM SHUTTING DOWN" and no other things when it happens. No errors or log changes or anything like that, just suddenly interjects the STOPPING! command and then shuts down my minecraft. Anyone know what would cause this?

*Edit*

Quick little edit after a few more tries and reinstalling the pack completely. I'm now getting an out of memory error it seems, still not sure what's caused it since I haven't done anything different to the files at all other than a reinstall and it's not a constant error either so I'm very confused.

You should go to Options -> Advanced Options and on Additional Java Parameters you should put

-XX:PermSize=128M

Hope that helps!
