# 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.
