Hello Stefano, 2.12 is quite old, and is has several bugs. Why not update it to at least 2.2.5? As for problems, there is a know bug when using mschap in 2.1.12, that often freeradius stops answering requests after a reload when rotating logs. You have to edit /etc/logrotate.d/freeradius and change the reload for a restart if that is your case. Another probable source of cpu/ I/O load is radwtmp and similar files, as they grow and are not rotated per the default configuration. I dont use them, I rely on the (My)SQL data. Hope these tips help you in some way. You are welcome to ask me any questions. Regards, Rui Date: Fri, 1 Aug 2014 10:57:48 +0200

Hi FR folks,
I got a strange cpu load on my FR installation. Sometimes CPU utilization rises to 100% and FR service doesn't respond anymore to the clients. I got two virtual servers enabled: default and inner-tunnel and their configurations are the provided ones by the FR installation. Configuration details in the following:
OS: Ubuntu server 14.04 Deamon: freeradius 2.1.12+dfsg-1.2ubuntu8 amd64 2 vcpu RAM 4GB
Users on freeradius MySQL (5.x) DB installed on a different virtual host on the same hosting server.
Hosting server (Ubuntu server 14.04 + Xen 4.3) HP PL G5 CPU: 2 x Intel(R) Xeon(R) CPU E7330 @ 2.40GHz - cpu cores 4; [total cores 2x4 = 8] RAM 16GiB
Do you have any ideas to solve my issue? Hope someone help me.
Regards Stefano
