This is the PID field in show system processes command output.

Individual processes on the Services Router are listed here. Because each process within JUNOS operates in a protected memory environment, you can diagnose whether a particular process is consuming abnormally high amounts of resources.

If a software process is using too much CPU or memory, you can restart the process by entering the restart command from the CLI.
