This is already way too large, unless you have some Fortran app.
Increasing maxssiz will decrease the amount of maxdsiz, if you have already increased it 4 GB.
>1: what is the maximum stack size will allow?
32 or 64 bit?
>2: How to set?
kctune maxssiz= or kctune maxssiz_64bit=
See your previous question:
