All I would add is "test, test, test".  If that goes well, and I'd
expect it would, implement incrementally and keep a backout plan
up-to-date.

we haven't seen the memory leak issue but also don't shutdown jails very
often.  If you do then a cron job might be indicated, something to check
rss and memfree and email an alert if needed.  That plus an NMS like
Zabbix should address the concerns expressed here.
