receive_secure_serial: bad database

[Eldridge, Rod A [ITNET]]

I haven't found a good explanation of that this log entry means:

Oct 20 14:41:47 dns-s named[8311]: zone student.iastate.edu/IN/in (signed): receive_secure_serial: bad database

I've found 58 log entires for this just in the last 90 minutes. Nothing before that in the last 9 days. I've also had named die several times for unknown reasons and once wasn't responding during this time as well.
