freeradius DNS issue

[Satish Patel]

I have two DNS entry in /etc/resolve.conf and somehow today 10.10.0.10
DNS went down and result radius fail to authenticate clients, it was
bizarre that 1 hour everything was down and as soon as 10.10.0.10 came
back radius start working, I have check 10.10.0.11 is totally
functional DNS but look like freeradius just doesn't like getting
failover to second DNS, is there any timeout or better solution of
this issue?

# cat /etc/resolv.conf
nameserver 10.10.0.10
nameserver 10.10.0.11
