(In reply to freebsd from comment #8)

I have tested it some time ago and it looks like ezjail is not able to shut
down the guest system in the correct way. If the child interfaces of epairb in
the jail are destroyed before the withdrawal of epair from the jail and jail
shutdown, then panic doesn't occur. 

>From the other hand, ezjail officially doesn't support vnet and is unmaintained
since a while.
