memory issue with latest beta 7 release of aTV flash (black)

I had no issues with memory prior to installing the latest Sept 6 release of apple TV  flash (black) beta 7 on my seasOnPass jailbroken ATV2. Now I am getting low memory errors on watching netflix movies after about 45 minutes of watching and I am getting low memory issues within a few minutes of watching movies over afp on the media center with mp4 encoded movies. Are there any workarounds or upcoming releases of aTV flash (black) that would help me to get around these issues?
