Well, it certainly seems like a buffer exhaustion problem but are you
sure?  What is the error code?  I'm guessing 123 - which could mean a
number of things.

There are many solutions to get around the common problem (which means
Google is your friend) of shell buffer limits .  Have you experimented
with the find "-exec" option?  Perl or Python scripts are great
solutions, and fairly efficient.  Maybe do several find commands, each
on a different directory branch?  Here's a simple, but very slow, bash
script.

#! /bin/bash

cmdfunc() {

    FINDOUT=/tmp/find.out
    CMDOUT=/tmp/cmd.out

    rm -f $CMDOUT

    find . -type f > $FINDOUT
    exec < $FINDOUT
    while read filename; do
      ls -lart $filename >> $CMDOUT
    done
}
