This is due to a limitation in the default size of shared memory in
Suns.  The file /etc/system requires the lines

* Large shared memory segment for 24-bit AIPS TV, from Dave Brown
*   GEM, 20 Mar 98
* harmless on systems that won't actually use it, so generic
 
set shmsys:shminfo_shmmax=8388608

Actually you do not need such a large number for pseudocolor 1142x800
- in fact I am suprised that the default 1 Megabyte does not work.

root has to change this file and then you should reboot the computer.
