Gies <heinz@project-fifo.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |heinz@project-fifo.net --- Comment #6 from Heinz N. Gies <heinz@project-fifo.net> --- I'm having the same problem and can reliably reproduce it. I noticed it when testing vmadm (https://github.com/project-fifo/r-vmadm) a= nd starting and stopping a jail a few times. The basic steps for start are: rctl -a jail:d0f4fea3-e368-4346-b44c-50cfbcffa287:memoryuse:deny=3D1024M jail:d0f4fea3-e368-4346-b44c-50cfbcffa287:memorylocked:deny=3D1024M jail:d0f4fea3-e368-4346-b44c-50cfbcffa287:shmsize:deny=3D1024M jail:d0f4fea3-e368-4346-b44c-50cfbcffa287:pcpu:deny=3D100 jail:d0f4fea3-e368-4346-b44c-50cfbcffa287:maxproc:deny=3D2000 mount -t devfs devfs /zroot/jails/d0f4fea3-e368-4346-b44c-50cfbcffa287/root/dev mount -t devfs devfs /zroot/jails/d0f4fea3-e368-4346-b44c-50cfbcffa287/root/jail/dev jail -i -c persist name=3Dd0f4fea3-e368-4346-b44c-50cfbcffa287 path=3D/zroot/jails/d0f4fea3-e368-4346-b44c-50cfbcffa287/root host.hostuuid=3Dd0f4fea3-e368-4346-b44c-50cfbcffa287 host.hostname=3Dtest devfs_ruleset=3D4 securelevel=3D2 sysvmsg=3Dnew sysvsem=3Dnew sysvshm=3Dnew allow.raw_sockets children.max=3D1 vnet=3Dnew vnet.interface=3Depair0b exec.start=3D"/sbin/ifconfig epair0b name net0p; /sbin/ifconfig net0p.5 cre= ate vlan 5 vlandev net0p; /sbin/ifconfig net0p.5 name net0; /sbin/ifconfig net0 inet 192.168.1.234 255.255.255.0; /sbin/route add default -gateway 192.168.= 1.1; /sbin/ifconfig lo0 127.0.0.1 up; jail -c persist name=3Dd0f4fea3-e368-4346-b44c-50cfbcffa287 host.hostname=3Dtest path=3D/ja= il ip4=3Dinherit devfs_ruleset=3D4 securelevel=3D2 sysvmsg=3Dnew sysvsem=3Dnew= sysvshm=3Dnew allow.raw_sockets exec.start=3D'sh /etc/rc'" ifconfig epair0a name j1:net0 and destroying the jail the same way in reverse (stop, unmount, remove rctl entries dstrouy j1:net0) kernel is FreeBSD fifo-bsd 11.0-RELEASE-p1 with=20 which is the standard kenrel config plus nooptions SCTP # Stream Control Transmission Protocol options VIMAGE # VNET/Vimage support options RACCT # Resource containers options RCTL # same as above I've uploaded the kernel dump here https://www.dropbox.com/s/73mb8e64cb7zwbe/crash.tar.xz?dl=3D0 (it's too big= to attach) --=20 You are receiving this mail because: You are the assignee for the bug.=
