Help phone restarts

[rickermeter]

ok i have an xperia x10 rooted...occasionally it restarts by itself. maybe once every 1 week or so...why is that?! its no biggie but it is annoying.
im only worried its goin to be a bigger problem in the near future

Depends what you have installed and how much you use the phone. Mine reboots itself once every 6-7 weeks.
