Comment 1 Petr Lautrbach 2016-11-01 10:34:03 UTC 
Red Hat Enterprise Linux version 6 is entering the Production 2 phase of its lifetime and this bug doesn't meet the criteria for it, i.e. only high severity issues will be fixed. Please see https://access.redhat.com/support/policy/updates/errata/ for further information.

This issue will be fixed in Red Hat Enterprise Linux version 7
