$ su -c "scodb -w"
Password:
dumpfile = /dev/mem
namelist = /unix
stunfile = /etc/conf/pack.d/scodb/defs/stun.def
varifile = /etc/conf/pack.d/scodb/defs/vari.def
PID 2CBF: scodb -w
scodb:1> maxexecargs=100000
100000
scodb:2> q
$ getconf ARG_MAX
1048576

This does not eliminate the issue. Also tried:

$ getconf ARG_MAX
16777216

Note, I have no idea that ARG_MAX is or is not relevant.
This documents something I did try based on a page that
came up in searches:

https://www.in-ulm.de/~mascheck/various/argmax/

[osr5] Bela Lubkin points out:
The limit on SCO OpenServer 5.0.x is set by 'unsigned int maxexecargs = 1024*1024;'
in /etc/conf/pack.d/kernel/space.c. It can also be changed on a live system with the `scodb` kernel debugger:

   # scodb -w
   scodb> maxexecargs=1000000
   scodb> q
(0x1000000 = 16MiB.) This is the max size of a new temporary allocation during each exec(), so it's safe to change on the fly.

Exceeding the limit generates a kernel warning:

   WARNING: table_grow - exec data table page limit of 256 pages (MAXEXECARGS) exceeded by 1 pages
   WARNING: Reached MAXEXECARGS limit while adding arguments for executable "ls"
Some `configure` scripts trigger this message as they deliberately probe the limit.
Raising `maxexecargs' will not fix this as the probe will simply try harder.
