Jails with VIMAGE and VLANS.

[Santiago Martinez]

Hi everyone, how you are doing well.
During the last months, I have been working with JAIL and VIMAGE to 
perform some network test/validations.

I have been facing the following weird behaviour that while it has been 
happening before, it used to be once in a while but now it is happening 
almost all the time.

When a jail is stopped, it seems that the interface associated with it 
is not released/de-associated to the no longer existing jail. This makes 
the system (no jailed) not to see the interface (using netstat / 
ifconfig) however it cannot destroy it or create it again (as it already 
exists).

Sometimes after a few minutes, the interface is "released" and it is 
visible again to ifconfig or netstat.

Is anybody else having the same issues? Any hints on how to debug this?

Best regards.

Santiago
