You referred to http://bugs.centos.org/view.php?id=6319 in your
earlier post. If you believe you are hit by the bug reported there, I
strongly urge you to test the centosplus kernel that has a patch (see
note 17700 of the bug report).

Regarding the current status, upstream BZ (
https://bugzilla.redhat.com/show_bug.cgi?id=887006 ) is open to the
public. It is "on QA" at the moment. I suspect the fix will be in
EL6.5 and possibly in a 6.4 kernel update.
