The Solution:
Add more semaphores with the semmns and semmni variables
in the /sys/include/sys/param.h (or the /sys/conf/HOST)
file. Also, to determine the number of semmaphores being
used and total number allocated use ipcs, ipcrm, and
"sysconfig -q ipc" (very helpful man pages for each command).
Once again, thanks a bunch. Hope I included everyone.
