# Test the ipc shutdown event. This event is triggered when the connection to
# the ipc is about to shutdown because of a user action such as with a
# `restart` or `exit` command. The `change` field indicates why the ipc is
# shutting down. It can be either "restart" or "exit".

# Ticket: #2318
# Bug still in: 4.12-46-g2123888
