It looks like your copy of radius is running netstat which is not 
exiting/being cleaned up properly. FreeRADIUS does NOT run netstat by 
default, so you probably have a custom module configured and it looks like 
it has issues. Maybe if you share your radiusd.conf we will be able to help 
you further...
