Sketch crashing suddenly when using Minim+OpenGL

I'm getting an "Invalid memory access" error along with an alert saying that OpenGL crashed when the following processing sketch runs for about 1-2 minutes, how can I fix it?

ERROR MESSAGE:

java(897,0xb1937000) malloc: *** mmap(size=1228800) failed (error code=12)

*** error: can't allocate region

*** set a breakpoint in malloc_error_break to debug

fft.forward(in.mix);



for(int i = 0; i < fft.avgSize(); i++) {

line((i * w) + (w/ 2), height/2 + fft.getAvg(i) * 3, (i * w) + (w / 2), height/2 - fft.getAvg(i) * 3);

}

}
