Check the basic settings first - notify, also-notify and similar.  If
OK, check transfers-in, transfers-out, transfers-per-ns and related
settings.  You might be hitting the limits if you are trying to transfer
a lot of zones.  I also seem to remember that there was a rate limit for
zone transfers on an IP basis.  Google.

It is called raw mode and is more efficient for named to parse than the
text file.  Check the named-compilezone command (see the -F option) if
you need the text format.

Consider upgrading to 9.9.1-P4.

In general, check the release notes / changelog.  See if there is
anything that affects you.  Compare with time/effort of upgrading.  Test
in a lab and deploy.
