Hi, I have setup a new freeradius server and today it died for the first time. Some info regarding the install: Version: radiusd -v radiusd: FreeRADIUS Version 2.1.12, for host x86_64-redhat-linux-gnu, built on Oct 3 2012 at 01:22:51 Copyright (C) 1999-2011 The FreeRADIUS server project and contributors. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. You may redistribute copies of FreeRADIUS under the terms of the GNU General Public License. For more information about these matters, see the file named COPYRIGHT. OS CentOS release 6.4 (Final) Some notes on my setup: Everything runs through mod_perl. So my perl script handles the DB connection, add and removes records from the DB and so forth. Its called for each and every request. I checked the logs when the server was down and the errors I saw were Sat Jan 11 16:26:08 2014 : Info: WARNING: Child is hung for request 67332 in component <core> module <queue>. Sat Jan 11 16:26:12 2014 : Info: WARNING: Child is hung for request 67329 in component <core> module <queue>.

Sat Jan 11 16:26:23 2014 : Info: WARNING: Child is hung for request 67331 in component <core> module <queue>. and those went on for HOURS. when i reached the top of those messages ( I assume just before the server failed I saw these logs come through) Sat Jan 11 13:19:00 2014 : Error: Received conflicting packet from client private-network-1 port 39484 - ID: 89 due to unfinished request 63062. Giving up on old request. Sat Jan 11 13:19:01 2014 : Error: Received conflicting packet from client private-network-1 port 53062 - ID: 244 due to unfinished request 63063. Giving up on old request. Sat Jan 11 13:19:04 2 Is there anything more I can do to troubleshoot and get more logs (exept run radiusd -X with nohup or something). Could it be my script causing this, or my DB or freeradius? Thanks for any advice
