Correct. It keeps a pool of LDAP connections open for future use.

In mods-available/ldap:

                 #  LDAP_OPT_X_KEEPALIVE_IDLE

                 idle = 60

Also look at the pool { ... } section, which in turn makes use of values 
set in the top-level radiusd.conf such as start_servers, max_servers etc.

I'm not entirely clear whether the errors you are seeing are because 
freeradius is closing the connection after 60 seconds of it being 
unused, or the server is doing so. Either way, there are knobs you can 
tweak.
