To remove the semaphores I use following script on my Digital Unix
machine (perhaps you must convert it to Solaris)

USER="$(whoami)"
if [[ "${USER}" = "root" ]];
then
   print "don't run this script as root"
   return 0
fi

for shm in $(ipcs -m |awk "/${USER}/ {print \$2}");
do
   print "removing shared memory segment $shm"
   ipcrm -m $shm
done

for sem in $(ipcs -s |awk "/${USER}/ {print \$2}");
do
   print "removing semaphore $sem"
   ipcrm -s $sem
done

I hope, this can help you.
