Are the zone journal files on the slaves useful for solving your problem?
e.g. my nameserver logs

If I run named-journalprint I can work out the contents the second IXFR
based on the SOA serial numbers, starting with the line deleting the SOA
with previously transferred serial, and ending with the last contiguous
add line after the SOA with the current serial.

becoming moderate. Fog patches in east, rain later. Moderate, occasionally
very poor in east.
