Howto debug Kernel problems ? (jail -r -> freeze)

[Denny Schierz]

hi,

If I stop a jail (v2 with vnet), the jail doesn't completely disappear. "jls" shows the jail as active. If I try to remove the jail with "jail -r <id>" the whole machine freezes. Other users with same options (i386) doesn't have this problem. So how can I debug it?
