Problems with my Qube 2

[Sevan / Venture37 <venture37%gmail.com@localhost>]

Hi everyone
My Qube 2 seems to crash every week or so with no explanation, the 
system is currently sitting at the db prompt, the output of which 
commands would be useful to give an indication of what makes the machine 
fall over?

trace output:
