EAP packets from 2 different upstream servers

They come because the packets for one EAP session are arriving from two
different upstream home servers.
Yup, know that, just want some info as to which upstream boxes they're
1). These boxes are our ORPS boxes and primary upstream boxes are the JISC
2). Or our Council has 1 RADIUS server that handles eduroam in York City
3). Our our clearpass cluster that handles internal auths and does its own
load balancing between our ORPS boxes.
Was hoping that debug mode would tell me a bit about what was happening ..
unless I need super debug mode !
>Running in debug mode shouldn't change the behaviour of the upstream
Granted ... but when I look in the normal radius.log and see the warning
message and run raddebug at the same time and in the same time interval
raddebug -d /etc/freeradius -t 900 > ./alex.log &
andthe radius log shows the message and the raddebug output doesn't ...
not sure how I'm supposed to see what is going on.
