** Description changed:

  When I use MATLAB and all 8GB of RAM are full, system freezes and only a
- hard restart can get it working. I have found that the same bug is
- around since 2007 in the bug report at
- https://bugs.launchpad.net/ubuntu/+source/linux/+bug/159356, but it was
- not fixed.
+ hard restart can get it working. I have tested it with the newest kernel
+ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc4-raring/ and it
+ still persists.
  
- Since Christopher M. Penalver insisted for re-reporting the bug and none
- have done it yet, I decided to report it. I have tested it with the
- newest kernel http://kernel.ubuntu.com/~kernel-
- ppa/mainline/v3.9-rc4-raring/ and it still persists.
+ Would need to increase swap space as outlined in
+ http://www.mathworks.com/help/matlab/matlab_prog/resolving-out-of-
+ memory-errors.html .
