I solved a similar problem on BIND 8.1.2 with the following patch

    Patch-ID# 106938-02
    Synopsis: SunOS 5.7: libresolv patch
    Files included with this patch:
        /usr/lib/libresolv.so.1
        /usr/lib/libresolv.so.2
        /usr/lib/sparcv9/libresolv.so.2

    Problem Description:
        4211042 Bind 8.1.2 in.named memory leak in Solaris 7

I hope this will help you.
