nfsidmapd is reporting lots of "Failed to add child keyring" messages in /var/log/messages

We may observe userid instead of username as a ownership of the files.

Ex.

-rw-rw----. 1 4294967294 4294967294 674 Feb 19 07:42 ./stocksys/algemeen/log/delabel.lst.124747

Instead of

-rw-rw----. 1 user group 674 Feb 19 07:42 ./stocksys/algemeen/log/delabel.lst.124747

Changes

Updated kernel from 3.8.13-68.3.3.el6uek.x86_64 to 3.8.13-118.2.5.el6uek.x86_64.
