I have freeRADIUS version 2.2.5 installed on Debian GNU/Linux 8.4 (Jessie). freeRADIUS use with telephone station. Now testing with two users. Their User-Names 682808 and 686038. When I run freeRADIUS as daemon, it works about one hour (sometimes less). Then I get for one of users: "Auth: [preprocess] No huntgroup access..." (log below). And another user can continue to work When I run FreeRADIUS in debug mode (freeradius -X), it can work for three days, I did not check longer. Detailed log, when user was authorize: Fri Jun 3 14:57:46 2016 : Info: expand: %{debug:3} -> 0 Fri Jun 3 14:57:46 2016 : Info: +++} # update control = noop Fri Jun 3 14:57:46 2016 : Info: ++} # if ("%{User-Name}" == "682808") = noop Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: calling preprocess (rlm_preprocess) for request 1434 Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: returned from preprocess (rlm_preprocess) for request 1434 Fri Jun 3 14:57:46 2016 : Info: ++[preprocess] = ok Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: calling auth_log (rlm_detail) for request 1434 Fri Jun 3 14:57:46 2016 : Info: [auth_log] expand: %{Packet-Src-IP-Address} -> 10.10.10.200 Fri Jun 3 14:57:46 2016 : Info: [auth_log] expand: /var/log/freeradius/radacct/%{%{Packet-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/auth-detail-%Y%m%d -> /var/log/freeradius/radacc$ Fri Jun 3 14:57:46 2016 : Info: [auth_log] /var/log/freeradius/radacct/%{%{Packet-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/auth-detail-%Y%m%d expands to /var/log/freeradius/radacct/10$ Fri Jun 3 14:57:46 2016 : Info: [auth_log] expand: %t -> Fri Jun 3 14:57:46 2016 Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: returned from auth_log (rlm_detail) for request 1434 Fri Jun 3 14:57:46 2016 : Info: ++[auth_log] = ok Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: calling files (rlm_files) for request 1434 Fri Jun 3 14:57:46 2016 : Info: [files] users: Matched entry DEFAULT at line 62 Fri Jun 3 14:57:46 2016 : Info: [files] users: Matched entry DEFAULT at line 65 Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: returned from files (rlm_files) for request 1434 Fri Jun 3 14:57:46 2016 : Info: ++[files] = ok Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: calling monthlycounter (rlm_counter) for request 1434 Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: returned from monthlycounter (rlm_counter) for request 1434 Fri Jun 3 14:57:46 2016 : Info: ++[monthlycounter] = ok Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: calling expiration (rlm_expiration) for request 1434 Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: returned from expiration (rlm_expiration) for request 1434 Fri Jun 3 14:57:46 2016 : Info: ++[expiration] = noop Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: calling logintime (rlm_logintime) for request 1434 Fri Jun 3 14:57:46 2016 : Info: modsingle[authorize]: returned from logintime (rlm_logintime) for request 1434 Fri Jun 3 14:57:46 2016 : Info: ++[logintime] = noop Fri Jun 3 14:57:46 2016 : Info: +} # group authorize = ok Fri Jun 3 14:57:46 2016 : Info: Found Auth-Type = Accept Fri Jun 3 14:57:46 2016 : Info: Auth-Type = Accept, accepting the user Fri Jun 3 14:57:46 2016 : Auth: Login OK: [682808/<via Auth-Type = Accept>] (from client localhost port 0 cli 682808) Fri Jun 3 14:57:46 2016 : Info: WARNING: Empty post-auth section.
