[PROBLEM] XBMC Crashes

[jackult]

today i've installed XBIAN BETA2, everything is going smooth..replace my old .xbmc dir, so i turned on a radio stream.....After a couple of hours my xbmc is starting to chrash, startup again, turned on stream again, then another crash......
I cannot find the crash of xbmc, these problems where the same i've in the beta 1.

Is this sounds familiar to anyone?

edit: on beta 1, i clocked my xbian, to 1000mhz, @ beta2, i clocked it @ xbain settings.
