Max zone transfer

Hi all!

I'm trying to send 500k records in a AXFR response, but I'm receiving the following error message:

DNS section count cannot be incremented -- org.xbill.DNS.Header.incCount(Header.java:218)
org.xbill.DNS.Message.addRecord(Message.java:157)

Is there any limitation in the DNS protocol related with the max size in a zone transfer?

Thanks,

Ok,

sorry, found the answer. The record counters (for example, ANCOUNT) present on the message have that limitation (unsigned int 16) .
