why so many fork???

[Thom]

so bad I have set the log lever to "error"
there is totally no log except the output to the console

I ran into some logging anomalies myself and ended up with no logs at all. I forgot how I resolved that.

Respectfully, may I request you @alt to review your P2P logs to determine if the multiple blocks received contain distinct hashes? Is it possible your P2P node(s) are receiving the same block multiple times? I hope to isolate our troubleshooting to either the block generation side or the P2P transport/receipt side.

If you can identify blocks from a given witness with distinct block hashes, this would indicate generation issues, introducing a deliberate fork.

Best,
Fox

Sorry you're experiencing these difficulties @alt.

In the future if you have such an (urgent) issue please use Telegram to reach witnesses more effectively and timely, as that is real-time communications.

sorry I'm busy on handle the fork issue for btsbots.com
I thought you have enable two nodes at the beginning
if it's not, I have no idea what happened
almost all bots from btsbots.com  failed when the fork happend again and again

I have to improve the code of btsbots.com to handle all these fork ASAP.

Can you elaborate on what you believe is going on? Are witnesses malfunctioning/misbehaving?

This is the witness node that generated the block(s) in question:

Each of my other witness nodes contain distinct signing keys, therefore I can guarantee that only a single [witness_node] program is able to generate a block. My logs do not indicate generating multiple blocks as indicated by your P2P log.

I am keen to determine why this occurring.

[Thom]

@alt, can you not get on Telegram witness alert channel?

[Thom]

The output of node does not indicate 2 blocks generated. A bug in code brought on by volume? Seems highly unlikely.

[Thom]

What makes you so sure the issue is with us? Logs log fine, just published feeds, memory fine, ~30 network connections, normal from what I have observed for quite a while now.

[alt]

these witness generate 2 block at the same time, so we got fork again and again
I don't know what's wrong with them

[Thom]

Indeed, please explain yourself

WTF are you doing?
