On RHEL4 a ulimit -a shows max user processes as 12287. /proc/sys/kernel/pid_max shows 32768 but I'm not sure whether this is the maximum number of processes or simply the largest value of PID before it rolls back around to 1. You could write a script that simply looped around kicking off sleep processes to test it. I remember reading somewhere that in the linux kernel mailing list there was discussion about making pid a bigger number (32bit instead of 16?) so a system could have more than 32768 processes at any one time but this was a while back.
You will notice on your system that when you run a phantom process, the port is listed >as "?", the phantom runs as a daemon at the Unix level and does not take a Universe >license.
For Ud (and afaik uv) this depends. If the phantom issues certain commands such as opening a server socket, it will consume a licence. There was an IBM advisory on this a release or two back.
