EGO has three types of dameons. See What Symphony daemons/processes are running on my cluster? and Where are the Symphony log files? How do I read them?.
EGO master daemons: Use egosh ego shutdown to shutdown EGO daemons on the current host.
EGO slave daemons: Use egosh ego shutdown to shutdown EGO daemons on the current host.
System services: Use egosh service stop <all | service_name> to stop services.
To stop both at the same time, use:
Windows; egoshutdown
Linux: egoshutdown.sh
