This issue begins to happen at about 14:48, May 3. Before that, app can be created successfully.
Comment 2 Thomas Wiest 2012-05-03 17:47:46 UTC 
This was caused by an errant lock file on /etc/gshadow.lock.

-rw-------. 1 root root 0 May  3 02:40 /etc/gshadow.lock

Dates / Time are EDT.

Clearing the lock fixed the problem.
