Re: One A record fails on one server on Sunday evening
How do I export the cache dump? rndc dumpdb on the first execute took a few seconds, but after updatedb locate named_dump.db (as it suggested it would store it there) returns nothing. The man page for rndc doesn't say anything about these commands either.

One A record fails on one server on Sunday evening
I have two servers that users query that as as cache servers. The server having the problem is CentOS 4.4 running bind 9.2.4 The second server configured similarly is CentOS 3.9 also running bind 9.2.4. There is one A record on Godaddy's DNS servers that fails look ups on the 4.4 server start around 7PM EST Sunday. I have been able to solve this each Monday morning by issuing the commands (rndc reload /etc/init.d/named restart). I have not had to do this on the second 3.9 server. I am looking for any suggestions or ideas to help fix this issue. Thanks in advance!

Re: One A record fails on one server on Sunday evening
The issue is that the A record no longer gets resolved. The command dig mail.alexandertelecominc.com @firstserver times out. Not sure what else I can provide that would help.

Re: One A record fails on one server on Sunday evening
It has happened the last 4 or 5 Sunday nights. Currently there are no logs - what categories would you suggest I start logging? The server comes back with simply no response. It just times out.

Do the logs on your 74.218.88.168 server tell you anything? Is there anything unusual logged prior to ~7PM EST Sunday? Again, without knowing more there is no way that we can identify exactly what occurred to cause the query to fail. Also, even with all the information that is available, we may still not be able to identify the problem. Then again, is this a one time situation or does it occur regularly?

Sherlock Holmes should never have been susceptable to this logical falicy. The opposite of the impossible is the possible, but no matter how improbable this possible may be, this is not the same as truth. A counter example, something occurs and there are three posited causes. One cause is impossible and can be eliminated. This leaves the other two possibilities, no matter how improbable. This does NOT make both, or either, of these possibilities the truth.
