Lots of "RSA_verify failed" after upgrade to 9.7.7

Yesterday I upgraded our slave DNS (running FreeBSD 7.4)
from bind to 9.7.7. The server uses bind97 from

After that upgrade I get lots of these in syslog:

RSA_verify failed error:04077068:rsa routines:RSA_verify:bad signature:/usr/src/secure/lib/libcrypto/../../../crypto/openssl/crypto/rsa/rsa_sign.c:263:

I have never seen these before.
I tried Google but got no recent results.
Anyone know what this means and how to get rid
of these errors?
