That might be it. It looks like you might have mangled the configs in 
/etc/radiusclient. This isn't a FreeRadius problem.

We use poptop/pppd/radius.so on RHEL4 x86 and RHEL5 x86_64, and the 
combination works reliably for us.

Where did you get your /etc/radiusclient configs from? Is the pppd 
package the standard one which comes with your RHEL distro - which pppd 
rpm version? Which version and CPU architecture are you running RHEL on?

I suggest you go back to the original versions of /etc/radiusclient 
configs and make small changes one-by-one until it either works or breaks.
