It's interesting that the value I see on my containers 
(9007199254740991) is the exact same value that's reported in this Red 
Hat bug. Clearly that is not a coincidence. We did not see this problem 
in 7.1 so apparently it is something introduced in 7.2. For the 
immediate term it looks like we'll have to roll back to 7.1.I'll look 
into getting it reproduced in Federa or RHEL.
