The important message is the first one.  You are attempting to write a
file > 2 Gbytes without having built the software for such large
files.  

Linux boxes with the 2.4.2 kernel (available in the infamous RedHat
7.1 release) and Solaris 2.6 and greater can compile the C routines
for this.  This requires the option

           -D_FILE_OFFSET_BITS=64

to be in your CCOPTS.SH.  We did not invoke this option by default
until 31DEC01.  In Solaris we have it in the CCOPTS.SH files for SUL
but restricted to our sites.


This does not restrict the total use of disk, just the use per file.
