Are the reverse mappings in your dns correct and complete?

Have you got the stops in the right places in the forward lookup?

Have got any stops in the wrong places in the forward lookup?

Try sending a SIGUSR1 to named to put it debug mode, and then look in the
debug output. Send named a SIGINT and inspect the namedb dump.

While in debug, send SIGHUP and check the debug output for errors found
when reloading.

Don't forget to SIGUSR2 named to take it out of debug mode!
