My xtrend box is locking up/freezing daily. Box is fast and working great but just locks up requiring me to power off and back on again..

Ive replaced hard drive with a brand new western digital scorpio as previous was second hand toshiba from eBay. Ive done a full reflash with latest vix image. I also do not use any plugins or anything really, just use it for sky UK.

It kind of reminds me of the memory leak the vu duo had...

Can anyone offer any help?
