ubuntu 12 guest crash

[michas84]

hello,
my virtual machine crashes recently after I boot it and launch chrome browser or gvim or any other application. I'm using virtualbox ver. 4.2.12 r84980 on win xp pro sp3.
I'm attaching my VBox.log as attachment (as suggested in error box). Any advice?

You are overcommitting your Host's available RAM.
Either increase your Host RAM or reduce the one given to the VM, or free up RAM by closing applications.
