Thanks for help Hugh.

I tried this, but the server is not crashing. It just stops processing. Added some debug in the
EAP_25.pm code and got this:

It seems like I'm stuck in the ERROR_WANT_READ block code, which does nothing, and this does
this all the time, wether I'm doing EAP-TTLS or EAP-PEAP. It looks definitely like a
Radiator/SSL issue, but I'm stuck by this lack of information.
First I guessed it was my version of OpenSSL (it was 0.9.6c), but after upgrading to the most
recent one, I still have this problem.

I'm looking forward to any suggestion one could have.
