If you look at 2.1.x changelog (from
http://freeradius.org/press/index.html for example), there were lots
of fixes after 2.1.7 was released, including stability fixes. Without
any additional data, my best advice right now is try rebuilding
Centos's freeradius2 SRPM, but update the source to 2.1.10.

Try 2.1.10 first instead of 2.1.11, as 2.1.11 requires some additional
fix (available in git).
