Named server (DNS) keeps failing every day


When I see my websites are loading slow, I need to login and re-start my DNS service and re-add an A entry for hostname.

During the time there is no A entry for hostname my server load goes sky high and it takes minutes before I can even login to WHM or even to SSH.

Re-adding A entry for hostname after restarting named service usually fix high load, but not always.

It looks DNS is not configured properly.

Do you have any suggestion?

Ps: I am also prepared to hire someone who have knowledge to fix those DNS issues.

Hi

If you log in via SSH then look at /var/log/messages, hopefully you'll see the named error.

If its Cpanel you could hire PSM to look at it.

Thanks

I've checked and I got MANY lines.

Here are a few:

Code:
Jun  8 21:19:56 server named[23607]: the working directory is not writable
Jun  9 12:20:46 server named[4978]: using default UDP/IPv6 port range: [1024, 65535]
Jun  9 12:20:46 server named[4978]: the working directory is not writable
Jun  9 12:20:46 server named[4978]: zone domain1.com/IN/internal: sending notifies (serial 2009072002)
Jun  9 12:20:46 server named[4978]: zone domain2.com/IN/internal: sending notifies (serial 2009072004)
Jun  9 12:20:46 server named[4978]: zone domain3.org/IN/internal: sending notifies (serial 2009072002)
Jun  9 12:20:46 server named[4978]: loading configuration from '/etc/named.conf'
Jun  9 12:20:46 server named[4978]: max open files (1024) is smaller than max sockets (4096)
Does this make any sense?

This flags some clue. Double check your BIND zone folders and make sure they are w/ the right permissions.

Thank you, but could you be more descriptive where folders located?

Again, I don't really mind hiring someone to fix in a proper way

If you want to hire people to fix this, you might have better luck in Systems Management Job Requests.
