2.0.12? Why? Even ubuntu's bundled version is at 2.1.12+dfsg-1.2ubuntu8.2
Or is it a typo?

- 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.
