your computer was restarted because of a problem

Hello there

I have a trouble here with my macbook pro (late 2008),today i had it on battery,was browsing the net,later i shut the lid(but not the macbook) and left it unattended for about 40 mins,then i opened the lid pressed any key,the message on the desktop appeared to shut it down with the power key and power it up again,which i did.The next thing i saw when i rebooted my macbook was that message with the log:
