We see the same behavior (also with nsd 3.2.16). It run stable until we 
started to make a lot of updates to the zone. 1 IXFR out of 4 fails and 
the automatic restart of the transfer won't also work. It needs an extra 
notify to trigger the transfer again (and then it works).

Did you discover anything? As you mentioned the source code does not 
give many hints.
