https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234985 Alexander Leidinger <netchild@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |netchild@FreeBSD.org --- Comment #3 from Alexander Leidinger <netchild@FreeBSD.org> --- With r349853 I don't get a panic with your script, but if I assign an IP inside the jail (jexec <id> ifconfig inet 1.2.3.4) instead of just listing the interfaces, it panics on destroy.
