servermgr_dns crashes – So What?

I managed my own DNS files manually; I learned to do it this way a while back, and never really felt comfortable with Apple's GUI. My nameservers work fine. However, whenever I use ServerAdmin, it tells the server to try to run servermgr_dns, which crashes for some reason. I get a dialog box error in SA every time it happens, and there's a corresponding message in the log. Lovely. This doesn't appear to be causing any real trouble, but it sure is annoying. Is there some way I can make servermgr_dns happy, or, failing that, stop it from running? What's it _for_? (10.3.9 Server)
