gigablue 800hd se memory leak?

Hi guys
I have had my 800hd se for a while but now it slows down terribly after a few hours and becomes completely unresponsive and I have to plug it out to get it going again. I think it may be a memory leak but I'm not 100% sure. I hope someone knows what the problem is and can help me
Thanks

I have openvix installed and I have tried with different images bit the same thing happens regardless

No its not a clone. I was hoping it was not the time to buy a new one.
