The AIPS on this system was not build to create and use files >2
gbytes in size.  You are not short of disk space actually, but the
file you wanted was too large.  This may be fixed on Solaris 2.6 and
later and on Linux with 2.4.4 kernel (??) now distributed as RedHat
7.2.  The $SYSLOCAL/CCOPTS.SH must specify the 64 bit option and then
all C routines must be recompiled (COMRPL) and all tasks rebuild
(INSTEP4).  Note that we changed to specify the 64 bit option all the
time in these 2 CCOPTS.SH files sometime this summer.  But systems
installed before then were probably build without this option (which
we used to restrict to our sites).
