Hi,
I have lived the same problem depicted here.
Alan De kok suggested to prevent the thread creation http://lists.cistron.nl/pipermail/freeradius-users/2007-October/msg00257.html . Is there another solution for that (maybe changing a sysctl value ) since machine has lots of memory and very less was used. We use freeradius 2.1.1 and rhel 5.3 x86
