or not, if it determines the serial is the same as the one it already has
and just reloads the zone...

so potentially a network issue could cause the domain to expire on my
secondaries, and not be able to be refreshed until named restarts, or the
primary sends a notify...

i am seeing the domain expire quite often, and also the named-xfer failing
with premature EOF, so i beleive the 2 could be linked, i have just seen a
further post from  Danny Mayer suggesting that bind8 on win32 has this
issue, so i am checking with the customer to find out what he is running.

Cheers guys
