I have an odd problem with Bind - which is driving me a little insane, and I cannot for the life of me find the cause.
I have bind setup on a box in my network to handle internal DNS. This is setup as a forwarder to a couple of other servers. All works fine. Randomly however, Bind will stop logging and stop forwarding requests. Requests that bind has zones for work fine, however it will refuse to forward any request to any of the 3 servers its set to forward to. There's also nothing in the log - once this starts happening, bind stops writing to the log.
I've tried changing the forwarders, and reinstalling bind - but it still does the same thing. Sometimes it lasts a day, sometimes it lasts a month, and restarting bind always fixes it. Any ideas what might be causing it?
(PS I should add that this DNS server is behind my firewall, so its not publicly accessible).
