Freeradius stops processing and ready to process requests loops

Hi Everyone,

We have been running Freeradius 2.x for many months on Ubuntu 14.04 LTS on a few servers. Our Ubuntu boxes were set to auto update and have been doing auto updates for 1-2 years without incident however this weeks updates appear to have broken Freeradius. Freeradius just stopped processing radius requests. When I ran in debug mode the "Ready to process requests." Just keeps looping down the page when radius packets come into the server and nothing is displayed, the radius log remains empty as well. If I run a tcpdump I see the radius packets coming in. We have 4 servers which exhibit the same symptoms. This morning the server auto updated and broke Freeradius again. Below are the packages that are being installed. Has anyone experienced this or could someone advise how else to debug Freeradius to see why it won't process requests as a result of these updates?
