Having trouble with OSX on a MacBook Pro.
My system randomly locks up, becoming completely unresponsive to mouse or keyboard, then after a few seconds shows the OSX login screen, at which point it is responding to the mouse and keyboard again. There doesn't seem to be any specific thing causing it, from what I can tell.
I was wondering if this has happened to anyone else and if so do they know how to fix the issue?
If there is any commands that I can run to give more information please let me know. If it happens again I'll be trying to record it to put up on youtube.
Bought from apple site in April 2013 so not an old one.

Updated with the log from is happening a few minutes ago.
