Unable to re-start machines, have to edit limits.

[GoogleCodeExporter]

Steps to reproduce:
1. "Stop" a machine
1.2 Change "disk space" or other feature
2. "Start" a machine
3. Receive error message - http://screencloud.net/v/tcff
if you try to start via commandline - http://screencloud.net/v/yBB9

4. Changing all limits to 0, save,  then change them back to "unlimited" 
resolves the issue.

Actual result:
http://screencloud.net/v/tcff

Expected result:
Machine starts


Version of the product:
2.4


Server OS:
Debian Wheezy

Browser:
Chrome


Additional information:
I have to go in and change all of the limits to "0", then save, and then change 
all the limits back to "unlimited" - then I can start the machine. This 
workaround works for us, but I thought I would report the issue.  THanks
