Interfaces handed to iocage jail don't get returned to the OS on jail stop

[chmeeedalf]

I have a jail that is multi-homed, one interface being a VNET interface, the other interface being a VLAN that I hand into the jail. However, on iocage stop <jail> the interface is not returned to the host until what seems like a timeout kicks it out, about 15 minutes later.

Details of the jail:
Runs home assistant, the VLAN interface is for a private IoT network (host doesn't need to be on that network).

config.json has:

"interfaces": "vnet0:bridge0"
"vnet_default_interface": "dpni0",
"vnet_interfaces": "iot"

It's also possible something's wrong with my config.

Looking closer, this looks to be something with the jail teardown, it's stuck in dying for that whole period. I don't know if there's a way to reap the jail forcibly, or do something else, to avoid this problem?

Thank you for reporting, I reproduced it, but didn't have time to find a proper solution now...
I'll take some more time this week
