DDNS another time

[Burkhard Weeber]

Hi,

after spending some hours on DDNS and slave severs I stepped on something
funny.

When the master is inserting dynamic entries and the .ixfr and .log files
are written after some time the NOTIFY goes out and the slaves do the
named.xfer.
So far - so good.

If the named process on the master now catches a HUP signal, it forgets the
current data and rereads the zone file. But this zone file is always
outdated and the slaves complain on the next notify "serial number < ours".

So back to my original question:

When and how are the zone files written.

For amusement:
Master on AIX3.2.5 (old but a lovely mess of *NIX dialects)
Slaves on AIX4.2.1, Linux RH6.2

Note:
If the linux box has a master zone it does not drop back the serial number.

Any hints anyone ?
