"If many ILE RPG programs are activated (that is called at least once)
system storage may be exhausted. Therefore, you should avoid having
ILE programs that use large amounts of static storage run in the OPM
default activation group, since the storage will not be reclaimed until the
job ends."

No, I was just drawing a parallel between how CGI programs are called from
an HTTP Server Job, and how 5250 programs are called from the command line.
When the CGI program runs in a named activation group, the resources it
allocates are scoped to the HTTP Server Job that called it.  They are not
reclaimed when the program ends.  So the activation of a lot of CGI programs
will exhaust RAM (CGI programs generally use a lot of memory, and other
resources).

As far as scalability is concerned, I suppose it depends on the amount of
RAM the box has?
