out of memory on read

[Morgan Fletcher <morgan@hahaha.org>]

I'm running mhonarc 2.4.7 with perl 5.6.1 on NetBSD 1.5. I have a set
of monthly archive files generated by majordomo. Mhonarc can't digest
one of the archive files:

  -rw-r--r--  1 lcmlarch  wheel  9811347 Jul  9 11:37 landcruisers.200106

The command line I'm using is:

  /usr/pkg/bin/mhonarc -add -savemem -rcfile \
  /usr/pkg/libexec/cgi-bin/.wilma/landcruisers.rc -outdir 200106 \
  landcruisers.200106

This is the output I get:

  Reading resource file: \
  /usr/pkg/libexec/cgi-bin/.wilma/landcruisers.rc ...
  Adding messages to 200106
  Reading landcruisers.200106 .Out of memory!

The machine has 512MB physical memory and a PIII processor. 

I couldn't find a debug or verbose flag for mhonarc. Did run it with
'perl -d', but didn't know what to look for in the debugger.

Advice?
