By 'debugging mode' I guess you are referring to radiusd -xxx or
something is that correct? Could this affect the authentication
service for our customers? 

I was thinking 
something in the lines of changing the freeradius config to log the
packets going to the home server and their replies (detail_log module
in pre_proxy and post_proxy stages).

Has anyone else noticed this behaviour in a large load proxy setup?
