I use Ubuntu 11.04 and it crashes every once in a while. I'm not sure what's wrong.

I use Unity. I tried Gnome Classic and even XFCE but it randomly crashes at times. Has been a very horrible experience. Can someone explain me what's wrong?

Most of the times I ll be using eclipse. And I did not find anything bad in syslogs but I find these in my gdm logs after every crash.

Has anyone faced similar issues?

I don't think those warnings/errors are serious enough to crash your machine. This looks more like a hardware/memory problem. Use the memory tester on the Ubuntu CD to see if you have a problem.
