bind 8.2.2-p5 ns_req errors with connection refused.

[foo at foobar.org]

Hey, all.

I keep getting ns_req connection refused messages like:

messages.Dec1899.gz:Dec 17 17:18:36 www5 named[5484]: ns_req:
sendto([192.168.254.192].2653): Connection refused
messages.Dec1899.gz:Dec 17 17:18:36 www5 named[5484]: ns_req:
sendto([192.168.254.209].1489): Connection refused
messages.Dec1899.gz:Dec 17 17:18:36 www5 named[5484]: ns_req:
sendto([192.168.253.244].1829): Connection refused

My version of bind is 8.2.2-p5 and it works fine, but at times (at what
seems to be random times) I will  get this error message and the DNS
server doesn't respond.

The only way I have found to fix it is to send a HUP to the named or
wait an undetermined amount of time for it to work again (it's
undetermined, because I send a HUP as more then 5 minutes and management
would be on my tail)

So any insight of why the DNS server is stalling would be appreciated.

Thanks. K.J.

P.S. My external DNS server works with no problems.
