solairs2.6+bind8.2.3 problem!! help!

[Kevin Darcy]

I run 8.2.3 on Solaris 2.6 all the time without these kinds of problems. Seems to me like named is just the victim of some sort of operating system problem
here. Are you sure your Solaris is patched up to date?

                                                                                                                                        - Kevin
