Java GC with Red5

I did some reading and it looks like this particular OOM message simply means to add more memory for the heap; it essentially means one is running too lean. CPU runs hot trying to clear the garbage.

OutOfMemoryError: GC overhead limit exceeded

Excessive GC Time and OutOfMemoryError
The parallel collector will throw an OutOfMemoryError if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection and less than 2% of the heap is recovered, an OutOfMemoryError will be thrown. This feature is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. If necessary, this feature can be disabled by adding the option -XX:-UseGCOverheadLimit to the command line.
