I would immediately suspect something on your network. Packet loss,<br>
mismatched MTU, etc.<br>
<br>
If I were you, I would run tcpdump on both master and slave and then<br>
attempt a zone transfer, and examine that packet trace. See what's going<br>
on. Are there TCP retransmits? Which side is stalling? The sender or<br>
receiver? What, if anything, do you see in the log files of your BIND on<br>
both the master and slave?<br>
