I'm doing an upgrade of a site from 2.2.x to 2.5.5. I've moved all of the files up, and prepped for the upgrade but when I run the upgrade wizard it is literally stuck on this screen: http://cl.ly/image/3r3L16453428
It will flash to say "Starting next step..." and then back to 2.3.0

Anyone else ever see this issue?
