Ok, I backtraced the coredump, the problem was in /usr/lib64/libssl3.so.
I updated from "nss-3.12.6-1.el5_4.x86_64" to
"nss-3.12.7-2.el5.x86_64"
and now all seems to work fine!
Thank you.

Dael Maselli.

Great! Be sure to install the 389-ds-base-debuginfo package to get the
symbols when generating the backtrace.
