DNS randomly bails out

[Red Squirrel]

Since I've setup this new server (FC9) My DNS server randomly bails out for external access. Internal DNS names work ok, but the caching DNS portion just crap out. There are no error logs or anything. What would cause this? I can go by IP so I know it's not my internet.

Right now this is the only site I can get onto since I happened to be browsing the forums when it happened again. This time it's worse then usual. Even restarting the services aint doing a single thing.

Actually in this case it was something else, but this is in fact a problem that keeps happening at random though it's been a while now... *crosses fingers*.

Are you sure it's your DNS server, or could it be the server upstream from yours?

You could try the OpenDNS.com nameservers:
nameserver 208.67.222.222
nameserver 208.67.220.220

I'm sure if it was the upstream most of the internet would be down. (I use large list of root servers)

Just happened again this time it was not another issue.

This is the errors I see in the logs. TONS of these, like probably a few 100 thousand.

Other name servers too, but spamhaus seems to be the one most seen.

Just happened again, it will be quit then all of a sudden start splurting out these errors for a good 5 minutes. (tail -f /var/messages).

Looks like named is furrnted. Guess I should try to reinstall it. Or is there any other solutions?

is your router handing out dhcp? if so, statically set your ip address to the server, then re set up dns and it shouldnt do it. it sounds like its changing its ip address (getting a new lease) and not restarting dns.

nah the DNS is a static IP of 10.1.1.10.
