ATV 2 crashes few minutes after startup

Hello,

I have looked around on the forum, but could not really find a thread with the same problem that I have.

My XBMC Frodo (12.0) keeps crashing on my ATV 2 (5.0.2). When I am watching a video, luckily, it is actually fine. But I think it crashes when my library is updating. I had the XBMC library auto update add on enabled but it kept crashing randomly. So I disabled this add on, and it seemed ok for a while (2 days or so without problems) Today it crashed, probably because I was asking too much memory or so, but then it kept crashing after startup every single time. After I reset the ATV 2 by keeping de menu and down arrow pressed for 35 seconds I can, most of the time, succesfully restart XBMC until the next crash. After the crash it restarts to the normal ATV 2 start screen, and when I try to start XBMC it starts, but after a minute or so it restarts the ATV again...

My videos are on a NAS (Synology) and I am using NFS for sharing (I have read somewhere that this is better than sambashare, although I can't remember why or where I've read this)

Here are the debug logs (last 2 crashes):

Her is a chunk of the syslog (total file is 111MB so I selected the last few minutes before the crash until the end)

and the last few crashreports: (none of them seem to be from today??)

If you need any more info, pls let me know!

thanks for your help!

edit: Forgot to mention, I have installed XBMC through NITOTV
