Does your RPi freeze?

[m_abs]

I have a similar problem, my 512mb raspberry pi often freezes. I experience these freezes with both playback and navigating trough files and collection.
I have a 1Gbit network and the files are shared over NFS. The shares are not mounted on the RPI, XBMC fetches the files directly.

I started having these problems right after the old microSD card died and I had to replaced it with a class-4 (because it was the only one I had), so I thought that this was the problem.
Unfortunately the problem didn't go away then I switched to a class-10.

Did you find a solution for your problem?
