Please don't use ALL Upper case for your text (hard to read!).

You need to increasing NSTREAM and NSTRPAGES (kernel parameter):

Value           Default         Min             Max
NSTREAM         64              1               32768
NSTRPAGES       500             0               8000

run scoadmin to change the kernel parameters (remember to relink the
kernel after change the value).

then reboot your box.

Please read the following docs:
http://docsrv.sco.com:507/en/PERFORM/streams_rsc.html

Good luck!
