This fails without fail every Sunday? In that case check what happens... eg if that HUP'ING of the freeradius is a weekly crontab then investigate what else is going on at that time ...eg there appear to be mysql errors - ate you using mysql? If so, its not good having errors with that module (and can be the cause if the problem...) I wouldn't say just stop that job....it has a purpose...but see if you are also eg dealing with mysql logrotating at the same time and if you are, don't.
I would advise doing a restart of the daemon rather than a HUP and contact your distro maintainers to get latest version. 2.1.10 is really really old. alan
