Hi,

its the end of 2014 - upgrade

clients.conf looks at the raw packet detailsm not the RADIUS datagram. its very likely that NAS-IP-Address
isnt in those packets - thus its not being logged. or the NAS-IP-Address is something different/wrong - eg hostname, MAC
address or IPv6 address or something b0rked.

this looks like a feature of the NAS  - some kind of caching or mobility going on? or is
the NAS configured to pass through the details after client has a known address? anyway,
full debug - but your server is old old old so no further help from me.
