A quick check here revealed, that IDL 6.0 und linux
(older Redhat, 2.4 kernel) IS limited to 2GB,
ie.
a=bytarr(1024,1024,2010)
works
a=bytarr(1024,1024,2020)
doesn't

And:
IDL> a=bytarr(1024,1024,1300)
IDL> b=bytarr(1024,1024,1300)
% Unable to allocate memory: to make array.
Cannot allocate memory
% Execution halted at: $MAIN$

HDH,
marc
