Unable to run [email protected] migrate --network live. "Exceeds block gas limit"

Question

I am using [email protected] to deploy smart contracts against a localhost:8545 [email protected] rpc, using an account that is funded with Ether has been unlocked using personal.unlockAccount on the geth console.

I have also tried the same against a remote Parity node via RPC, but this is the latest which I am rather stuck with.

truffle.js

module.exports = {
  build: {
    "index.html": "index.html",
    "app.js": [
      "javascripts/app.js"
    ],
    "app.css": [
      "stylesheets/app.css"
    ],
    "images/": "images/"
  },
  rpc: {
    host: "localhost",
    port: 8545
  },
  networks: {
    "ropsten": {
      network_id: 3,
      port: 8548, // ssh tunnelled to AWS geth/parity node localhost:8545
      from: "0x4f000Bcf4641E2fDcE85BF26A694b053996850D4"
    },
    "live": {
      network_id: 1,
      port: 8545,
      from: "0x00269400181f1B379784BD8cDF786bb20e91Bdef",
      gas: 4612388,
      gasPrice: 2776297000 // taken from Parity startup log message "Updated conversion rate to Ξ1 = US$42.88 (2776297000 wei/gas)"
    }
  }
};

truffle migrate --network live

I have tried adjusting gas and gasPrice, but am unable to find values that have any affect.

How can I solve this problem, or are there alternative contract deployment methods I should look into?

Kind Regards.

Answer 1

I was able to solve this by simply setting gas: 3000000 in the network config.

"live": {
  network_id: 1,
  port: 8545,
  from: "0x00269400181f1B379784BD8cDF786bb20e91Bdef",
  gas: 3000000
}

It cost about 0.5 ETH to run migrations and took several minutes.

Answer 2

In my case the problem was generated by a user's empty balance.

so check your balances using the following function :

function checkAllBalances() {
    var totalBal = 0;
    for (var acctNum in eth.accounts) {
        var acct = eth.accounts[acctNum];
        var acctBal = web3.fromWei(eth.getBalance(acct), "ether");
        totalBal += parseFloat(acctBal);
        console.log("  eth.accounts[" + acctNum + "]: \t" + acct + " \tbalance: " + acctBal + " ether");
    }
    console.log("  Total balance: " + totalBal + " ether");
};
 checkAllBalances();

if the balance is 0 mine some blocks or edit your genesis file.
