Hi, I've just downloaded,compiled and installed the latest version of 2.2 (2.2.1?) from git.freeradius.org.
Installed it on an internal server and things seemed to work o.k. I then upgraded another server that deals with our external ( eduroam) connectivity and within a few mins am seeing Thu Mar 7 10:25:58 2013 : Error: WARNING: Unresponsive child for request 16, in component <core> module <thread> Thu Mar 7 10:25:59 2013 : Info: WARNING: Child is hung for request 16 in component <core> module <thread>.
