You likely need this upstream commit:
http://git.kernel.org/linus/19fa1a6756ed9e92daa9537c03b47d6b55cc2316
Though that commit was tagged for stable. So not sure.
In general, upstream dm-thinp saw quite a few improvements that in
combination results in a much more stable dm-thinp (particularly error
handling from faults and out of space conditions).
RHEL7 does include these changes.
