On our Freeradius 2.0.12 on Ubuntu 14.04 server, we are sometimes experiencing repeated service restarts.
2.0.12? Why? Even ubuntu's bundled version is at 2.1.12+dfsg-1.2ubuntu8.2 Or is it a typo?

Any ideas what cause the freeradius service to stop and restart repeatedly like this?
- do you run latest version of FR (or at least, latest available from your distro)? - does it happen often, or only on that specified time? - does something happen on that time that restart freeradius (e.g. logrotate, apt-get upgrade, or something)? - does FR access external things (e.g. database)? What is the state of those systems at that time? The usual troubleshooting methods would be 'run freeradius in debug mode and read the logs', but it might not be able to help you much if the problem is due FR being restarted. -- Fajar
