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

If a software process is using too much CPU or
memory, you can restart the process by entering the
restart command from the CLI.
The total usable flash memory is the total memory
minus the size of the JUNOS image installed on the
Services Router.
