Second thing do not u= se the "service jail" command to start/stop your jails. Use the native jail(8) command instead. It's bad practice to mix the use of the old way and new wa= y of jail control. I would not call this a work-a-round for your problem, but mo= re like the correct intended usage. As a side affect your jails will start/stop faster. --=20 You are receiving this mail because: You are the assignee for the bug.=
