While RedHat does a lot of back porting of fixes and makes their version numbers often meaningless as a result. Do you know what that translates to for equivalency? Can you use something a bit more modern?
Bind 9.3 went EOL in January 2009, so I would try with something else.
It's still supported by Red Hat, but the latest version is bind-9.3.6-25.P1.el5_11.9.
If you’re on RHEL5 support may have already ended unless you’re out to the March 2017 date.
Even on Red Hat Enterprise Linux 5, you can install the bind97-utils package, which will give you a less ancient version. (Obviously, moving to a newer version of the operating system is strongly recommended at this point.)
Due to this, please try with something else perhaps?
Or at least use more realistic dig flags, such as “+norecurse +dnssec +trace +all”. In older versions, dig emulated stub resolver behavior even with “+trace”, so the default flags were pretty useless for testing.
