HAve a look at bind-9.3.0 and it's ability to create
IXFR on static zones.

Read about "ixfr-from-differences  yes;" which does the magix.

The slaves already tries ( according to the logs shown) IXFR, so whenever 
you upgrade to bind-9.3.0 these problems will disappear.

I've been using this for a dnsbl and it works like a charm
