BIND 9.2.3 and zone transfers larger than 64MB

[Mark Hennessy]

I am using MAPS RBL+ and their zone file has recently (in the past few =
weeks)
grown to be larger than 64MB.  I have been using BIND 9.2.3 prereleases =
and
have upgraded to 9.2.3 GA recently.

I get the following output in my logs:

Aug 27 08:45:17 <host> named[83125]: transfer of =
'rbl-plus.mail-abuse.org/IN'
from <mail-abuse.IP>#53: failed while receiving responses: out of memory

My named process also dies every few hours or so.

Is there any recommended course of action to take to fix this that does =
not
involve going back to BIND 8?
