BIND 8.3.1 on NT 4.0 in private network.
The following error messages have been logged in our DNS log every couple of minutes. It seems to me the slave nameserver tried to do a zone transfer of and never got completed and therefore it is re-trying every other minute.  I am the master (primary):

03-Feb-2002 01:48:03.000 zone transfer (AXFR) of "" (IN) to [].2586
03-Feb-2002 01:48:03.000 stream_getlen([].2586): Errcode: 9: Bad file descriptor

The slave nameserver is a WinNT DNS.  I have at least three other slave DNS have the same problem.  I have checked Google but similar questions (3) were never answered fully (ie. no definite solution was recommended).  Hope I'll have better luck than the others.
