zonec fails on fairly large zone

[Joseph McDonald]

Hi,

I have just started with nsd.  I attempted to create a database of the
net zone, after a couple of minutes I get:

zonec: malloc failed: Cannot allocate memory

The zone file is this large:
% wc net.zone
 9533163 28599507 314469843 net.zone

The machine has a couple of gigs of RAM.  The malloc seems to occur soon
after the process size reaches 500 megs.  There is still well over a gig
of free memory.

Any ideas what could be causing this?

thanks,
