I'm going to toss out a suggestion of 4.3.0 ... yes, .0! It was 
released quite some time ago, and is not having the kind of issues 
one might expect with a .0 release <cough>BIND 9.10.0</cough>. It 
also has a greatly enhanced feature set.

If you're going to upgrade anyway (and in this case I agree, OP 
really should upgrade), it makes sense to go to the most recent 
stable release.
