	# This script monitors a Jormungandr node for "liveness" and executes a shutdown if the node is determined
	# to be "stuck". A node is "stuck" if the time elapsed since last block exceeds the sync tolerance
	# threshold. The script does NOT perform a restart on the Jormungandr node. Instead we rely on process
	# managers such as systemd to perform restarts.
