https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203175 --- Comment #6 from Palle Girgensohn <girgen@FreeBSD.org> --- I got a fresh core dump from another machine with the same setup. WITNESS, VARIANTS etc all turned on. Attached the quite long out put from "info threads" as well. We *really* need to find a way to stop our servers from crashing, so any help appreciated!
