It appears that you have hit the 2 Gbyte limit which older systems
impose on individual files.  AIPS is capable of writing larger files
(except as FITS disk files) on systems that are modern enough and for
which AIPS was properly installed.  What operating system are you
using (enter uname -a and send us the output) and what version of
AIPS?
