The table identifier does not refer to an existing ETS table

[samuelventura]

I do not know how to replicate this but it has happened a couple times in the BBB. Rebooting the device wont fix it.

iex(5)> VintageNet.info
** (ArgumentError) errors were found at the given arguments:

I've seen this happen when the :vintage_net OTP application isn't started. I'd expect that there will be some exceptions from RingLogger.next. You could try Application.ensure_all_started(:vintage_net).

Having said that, I think that I can improve the error message. But let me know what happens since improving the error message obviously won't help you fix the issue.

We were able to replicate the problem by configuring an address and gateway in different network segments. That is a user error of course but since the impact is large (vintage app won't start any more) vintage should reject such invalid params. We also confirmed that removing the vintage folder in /data partition and rebooting brings the BBB back.

iex(3)> VintageNet.configure("eth0", %{type: VintageNetEthernet, ipv4: %{method: :static, address: "10.77.1.100", prefix_length: 24, gateway: "10.77.0.1", name_servers: ["10.77.0.1"]}})
:ok

Could you post the commands needed to replicate the issue?

Oh, sorry, I didn't scroll to the right. I see it.
