This isn't the kind of tuning you'll want to test but anyway here is an example of a script that will test this limit and more than likely crash your OS:

#!/bin/ksh

count=$(sysdef -i | grep maxup | nawk '{print $1;exit;}')

print "Launch $count processes (WARNING: this WILL brick your system ...) y/[n] : ? "
read yesNo
if [ "$yesNo" = "y" ]
then
        echo starting ...
        while [ $count -gt 0 ]
        do
                /usr/bin/sleep $count &
                count=$((count-1))
                printf "%06d\r " $count
        done
        sleep 30
        ps -ef|wc -l
else
        echo "Cancelled"
fi

I didn't tested it. :smiley:

thank you ! don't worry about this. this test is proof for theory and i don't use maxprocess from sysdef but this test need real max process from usable
