I see similar messages in 9.9.0rc2, where I have configured a server to receive unsigned zones for DNSSEC inline signing from a bind10-devel-20120119 hidden master and to serve the signed zones to two bind10-devel-20120119 slaves:

Feb  4 15:53:46 nsb0s named[9090]: zone jspain.us/IN (signed): zone serial (2012013003) unchanged. zone may fail to transfer to slaves.

The 9.9.0rc2 server is configured with the option "notify explicit;" and the zones, which are of type slave, are configured with masters { <address of bind10 hidden master> }; and "also notify { <addresses of bind10 slaves> };". Is it this particular configuration that triggers this message? or should I look for other issues? or should this message be ignored in this context as well? Thanks. Jeff.
