Program too large problem....

[Robert Dal Santo]

ENVIRONMENT:

    Running xenix 2.2.1 on a 6 Mhz AT with 3.2Mb I have encountered a 
    problem in running a program - "too big" (from sh).  Size gives me:

	program:  124937 + 51766 + 17914 = 194617 = 0x2f839

PROBLEM:

    The exec returns with

	errno = 12  (ENOMEM?)

    Intro(2) tells me that this error can be caused by either too many
segments, not enough physical memory, not enough swap space, or by exceeding
a system-defined parameter.  I have 2556 blocks in my swap device, a maximum
user process size of 1917k, and I have used the -NM cc option to limit
the number of segments, so my only option would appear to be increasing 
the latter system-limit.

    I've had a bit of a look around /usr/sys, but I can't find any obvious
parameter which I can increase before re-linking a new kernel.

    I've tried to use "runbig", but whilst this program quite happily
execs normal programs (which can run on their own) it reports that it
"can't find" my errant too-large binary, no matter how I try to invoke it.
Just when I need it most ...

   I've also tried to run "program" with no other processes executing
other than init, swapper(!), getty and sh, to no avail.  Same running
single-user.

    I've also tried calling the "proctl" system call under root to
lock large programs in core (helpful when the swapper can't accomodate a
large program) but still get the same errno=12 on the following exec().
Another pointer that swap space is not the problem?

    Could someone please give me some help on what I can do?  There doesn't
seem to be much documentation on "tuning & relinking the kernel" or have
I (I hope not!) missed reading something?

Thanx.
