In my .tcshrc, I have

    limit datasize      unlimited

but beyond that I don't think there's anything special about my setup.

The config file is attached.

Interesting idea but...

     $ ls -ls massive*
     1485872 -rw-r--r--  1 rob  wheel  1520772480 Sep 25 22:37 massiveFile
     922064 -rw-r--r--  1 rob  wheel   943718400 Sep 25 22:39 massiveZeroFile

where they were created by (in effect)

    dd if=/dev/zero bs=100m of=massiveZeroFile

and

    cat /etc/hosts massiveFile >> massiveFile

As you can see the file of zeroes is smaller than the text file but
the text file works just fine and the file of zeroes behaves as reported.

I don't have enough free filespace to create 4Gb files.

GENERIC_LAPTOP doesn't run on my laptop, hangs at RaidFrame init,
so I can't try that.  I'll try supping and updating my system.

Thanks for your help!

Bob

PS: I've just tried 'less' from pkgsrc of a few days ago.
    It behaves differently on the zeroes file.
    It burns 100% of the CPU but uses relatively little memory.
    It is however unresponsive, eg I cannot ^C it or suspend it.
    On the large text file all works fine, just like the NetBSD version.

# mode to use, the next set of four bits the DMA mode and the third set the
# UltraDMA mode. For each set of four bits, the 3 lower bits define the mode
# to use, and the last bit must be 1 for this setting to be used.
# For DMA and UDMA, 0xf (1111) means 'disable'.
# 0x0fac means 'use PIO mode 4, DMA mode 2, disable UltraDMA'.
# (0xc=1100, 0xa=1010, 0xf=1111)
