Try a different Ruby version? Say 1.9?

stephenfewer commented

Hi, it seems Ruby 2.0.0 segfaults in a non deterministic way. The best solution is to do what @wchen-r7 mentioned and use ruby 1.9.3, so long as you are only fuzzing x86 browsers as ruby 2.0.0 x64 is needed for x64 browsers.

Alternatively, I have just let grinder crash and bring up the instance again and eventually it stays up. Not a great solution but its the only workaround until the ruby 2.0.0 issue is identified and addressed.
