Failed oracle db connection kills the freeradius service

Thanks for your reply, Alan.

Downtime could happen sometimes and I understand I can just comment out a
module when the SQL server goes down, but sometimes it could be out of our
control, a database can fail for hours and I thought there might be a way
freeradius can just "deal" with failed mysql connections by rejecting if
the source is unavailable.... I don't mean that freeradius "should" deal
with it, by any means, just to have the option of rejecting if the auth
source is unreachable.
Does this mean the same behavior can be expected if I'm authenticating
against LDAP and the LDAP server goes temporarily down?

Thanks again
