HP-UX 11i v3 deprecates STREAMS/UX supsched process
On HP-UX 11i v3, the usage of the supsched process has been deprecated, leaving only smpsched. The kernel parameter NSTRSCHED still control the number of smpsched processes, the system determines the number of daemons to run based on the number of processors in the system (0) or a positive non zero tunable value is the number of "smpsched" daemons that will be created on an MP system.
Command like "ps -ef | grep [s]upsched" will not show any running process in current HP-UX 11i v3 systems.
HP and third party process monitoring tools configured to monitor this process, may produce errors messages on HP-UX 11i v3 systems were the process is not longer used.
