The config limits chart for SL covers only V3 and 4, so I don't know for
sure.
Red Hat has a chart covering RHEL 3, 4, and 5, indicating a drop in
supported
maximum per-process memory, from 4gb to 3gb, for V5 over the prior versions:
http://www.redhat.com/rhel/compare/
I don't see hugemem kernel anywhere, not since SL 4 anyway.
To get 4gb I could run an earlier SL I suppose, or steal its .config file &
roll
a new hugemem kernel...or better yet, code review the program asking for all
that memory
in the first place :-\
Actually, that will be my tack...push it back on the developer : )

I imagine you're wrong. I expect the base kernel does what the kernel+
variants have done in the past.
If thats the case...would 64-bit SL5 allow more per-process memory?
I expect you're right:-) I understand it's also quicker.
Especially if you add even more RAM. I've discovered one of my desktop
supports 2 Gbyte DDR2, so it might get some on the "chuck 1 add 4" plan.
Wouldn't work at all well with IA32.
