I think I know why testnet-1 has halted! #4

Closed alkadeta closed 3 years ago

alkadeta commented 3 years ago

So this morning at least 20 or 30 validators whom have been using Google Cloud Provider have been banned and their virtual machines which their kira nodes have been running on, got shutdown by Google support. Reasoning was Cryptocurrency mining. Some of them reached out to support and got their issue resolved but some of them were not that lucky.

So, I believe this is the issue that caused the testnet-1 to get halted. This is just a theory but I've heard from at least 10 people, some of them are my friends some of them are Kira community members, that they have been banned at the same time on Google Cloud Provider. Their only similarity was that they all have been running Kira Network Testnets.

I believe if you look at the logs you will see that, so many validators got cut off at the same time frame and this might be the reason consensus or network has halted. You can ask the community about the Google banning people for Kira node, you'll probably see more than 30 people.

Just my 2 cents on the situation, wanted to share with y'all. Thanks and looking forward to the Testnet-2!

probably you are right -- based on the below logs, some validators were caught in shambles ++ jq -rc .consensus_stopped ++ echo {"height":"49999","round":0,"step":"RoundStepCommit","start_time":"2021-04-02T09:52:43.356426452Z","commit_time":"2021-04-02T09:52:46.050147418Z","triggered_timeout_precommit":false,"proposer":"kira10flmchgzq90elwmqpgt5fnp6cfgsctte0vwpsa","precommits":["kira1ekwqt3l2tgasj7p2dyhpd3yfy43f3zke9tqt2v"],"prevotes":[],"noncommits":["kira12ycnw3djqnj347q9h5ppf8sswjlrc5n3pg4nl2","kira1ux58h85fh75se3np26zscsu4wle7h0x29nuesq","kira1kdkmg0exjhdwyndydwadf9c7apsqrxhf9n7jrw"],"average_block_time":7.935450048927537,"consensus_stopped":false}

Yes! thank you. I think we found the issue! I'm questioning some community members currently and so many of them got banned this morning. I believe my theory is correct 👌

Strange thing, cause the precommits on the last block seemed to be there: "precommits_bit_array": "BA{69:xxx_xxxxxxxxxxxxxxxxxxxxxxxxxxx_xxxxxxxxxxxxxxxxxxxxxxxxxxxx_xxx_xxxx} 65/69 = 0.94"

This is my log from validator when the issue occurred:
