debug.witness.watch=0 disables witness watching -1 turns it off altogether (and according to the code requires a reboot, but I haven’t tested that assertion). As for all of the LORs reported, I’ve seen them a lot running CURRENT and at $work :(... I’m working on printing out those stacks via log(9) though — I’ll publish my new diff on Phabricator soon: https://reviews.freebsd.org/D1794 . Cheers!
