Use the seed node 188.165.233.53:1777

that helped me to sync the chain!
Thanks,

Can somebody mention more seed nodes? So we are not depended on a single seed node?
How can we run a dedicated seed-node and give them a specific port available to others? (without using it for block production)

[Spectral]

Witness spectral stopped producing blocks and started producing error messages at the witness output. Here is a log from the screen buffer of the witness output:

https://drive.google.com/file/d/0BzEEZBS7b6xPUnJvQXFZUHZQZW8/view?usp=sharing

Did this also happen to the others?

I deleted oct5 and object_database, restarted witness, and it's back to producing blocks and price feed.

[bytemaster]

here is my automatic failover script powered by xerocs python-graphenelib.  I am a noob at teh programming, and if I did anything wrong I would love the feedback.

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import sys
import json
from grapheneapi import GrapheneWebsocket, GrapheneWebsocketProtocol
import time
import config

rpc = GrapheneWebsocket("localhost", 8092, "", "")
publickeys = config.publickeys
witnessname = config.witnessname


def getmissed(witnessname):
    witness = rpc.get_witness(witnessname)
    missed = witness["total_missed"]
    return missed

missed = getmissed(config.witnessname)


def switch(witnessname, publickeys, missed):
    keynumber = missed % len(publickeys)
    key = publickeys[keynumber]
    rpc.update_witness(witnessname, "", key, "true")
    print("witness down switching to " + key)
print ("Nothing in this window will change unless a block is missed")

while True:
    if missed < getmissed(config.witnessname):
        missed = getmissed(config.witnessname)
        switch(witnessname, publickeys, missed)
    else:
        time.sleep(3)

You need to add two lines to your config.py file.  witnessname as a string and publickeys as strings in a tuple of the public keys you want to switch between.  those lines look like this in my case.

witnessname = "dele-puppy"
publickeys = ("GPH75xxKG4ZeztPpnhmFch99smunUWMvDy9mB6Le497vpAA3XUXaD", "GPH8Sj81ncf8PK5QwJZvhWsvwp6m4bXzTFvp4bKycNNFvHaJpZSnH")


The wallet this script is running through needs to be unlocked, and must contain the owner key (I think its the owner key, rather than the active key) of the witness.

Nice!

I would not assume that all missed blocks are the fault of your witness or an indication that you need to switch nodes.    I would probably use the "last_confirmed_block_num" property on the witness and only switch if it is more than 3 rounds behind the head block number.

Is there any possibility to get market history or how to get asks/bids. I tried with get_market_history but there always is an empty array []

Many delegates went in a big minor fork (~35% partecipations) and also spartako and spartako_bot

I removed the blockchain and resynced with the main chain using this seed node:
188.165.233.53:1777

This is the error then I found:

I'm planning 100 TPS test at 10/9 21:00 (about 4 hours after the next hardfork). Is it reasonable?

Could you do it a couple of hours earlier?

[Thom]

What is happening? I'm not seeing regular updates in the witness. I did see this:

1586211ms th_a       application.cpp:529           get_item             ] Couldn't find block 00018ad
87629d33a99b65f537b4ddbb1af721828 -- corresponding ID in our chain is 00018ad87629d33a99b65f537b4ddbb
1af721828

Did the chainID change without an announcement of a new test?

I have not stopped the witness since I updated the binaries. It was fine a few minutes ago, but now nothing.

[Thom]

I updated last night at 9PM, so I am ready for the hard fork. Witness is working again on the original keys. Not sure why I can't switch to new keys with update_witness as I did on Wednesday, but I'll find out why after this morning's mumble.

I missed only 1 block since 9PM last night.

[xeroc]

could the witnesses please give their opinion on this matter?
