The last time i visited this link it was dead (403), so I cloned it here from the latest snapshot in Archive.org's Wayback Machine https://web.archive.org/web/20170523131633/https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/

	launchctl print gui/$UID

	# dump details of the service

	# stop service and unload from launchd
	launchctl bootout gui/$UID/com.blakegarner.vault

	# start the servcie and load plist from disk
