Hello Stefano,
2.12 is quite old, and is has several bugs. Why not update it to at least 2.2.5?
ok I'll do upgrade asap, but I'm not sure this will be feasible in near future. I'll try to fix it on this installation first.
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. actually the problem seems to be not related to the log rotate operation, however I changed it as you suggest me.
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. I'm going to change this configuration too.
Hope these tips help you in some way. You are welcome to ask me any questions.
Regards, Rui

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
