Issue

I ran truffle migrate --network main, with my Geth running the main net. At every step, I would get:

Error encountered, bailing. Network state unknown. Review successful transactions manually.
Error: Exceeds block gas limit

Steps to Reproduce

Do truffle migrate targeting the main net.

Expected Behaviour

I would have thought that a reasonable amount of gas would be given to the transactions.

Actual Results

  • When it did deployer.deploy(Migrations); I got this block gas limit error.
  • So I changed the line to deployer.deploy(Migrations, { gas: 300000 });
  • Then when it did, behind the scenes, migrations.setCompleted(1), again I got block gas limit.
  • So I did this .setCompleted(1) by hand within Geth
  • Then when it did deployer.deploy(MyContract); I got this block gas limit error.
  • So I changed the line to deployer.deploy(MyContract, { gas: 300000 });
  • Then when it did, behind the scenes, migrations.setCompleted(2), again I got block gas limit.
  • So I did this .setCompleted(2) by hand within Geth

On my Geth console, I noticed the following:

> eth.getBlock("pending").gasLimit
4709181
// Wait for a block
> eth.getBlock("pending").gasLimit
4704588

In your truffle.js, can you reduce rpc.gas a tiny bit and see if that helps?

Like so?

  rpc: {
    host: "localhost",
    port: 8545
  },
  networks: {
    "main": {
      network_id: 1,
      gas: 500000
    }
  }

Your value (500000) seems rather low. The default value is 4712388.
Try with the default or lower it to 4612388. Not sure why but it then worked on my end...

Resolved by the solution found @ stackoverflow from user Matthew Schmidt

Possibility two: you're giving the transaction too high of a gasLimit. If the transaction has a limit of 2,000,000, it'd stop you since it could theoretically go over the block gas limit, even if in practice it won't. If this is the case, see if you can reduce the transaction's gasLimit while remaining above the amount it actually needs--that might do the trick.

If I set the gas in truffle.js to 4500000 I get out of gas. If I set it to 4750000 i get exceeds block gas limit. I could continue the trial and error binary search of the gas space, but I suspect there may be no gas number that satisfies both constraints. What do I do?

As you describe it, your problem is with your contract constructor.

Also had this gas deployment issue with truffle 3.4.11. Changing the gas limit didn't help me (already had mine at 4M), but two things did the trick:

  • update testrpc to latest npm install -g ethereumjs-testrpc
  • i had a function declared but not implemented in my contract (function myfn(uint256 _count);), and apparently that was causing unreasonable gas estimates?? Removing it fixed the problem

Here's result for truffle 4.0 with testrpc, at old MetaCoin example.

4712388 = out of gas
4712389 = Exceeds block gas limit

But it working fine in truffle develop just broke external testrpc

Any idea for magic number?

I had the same issue with truffle 4.0.1

this is my workaround

$ truffle console
truffle(development)> web3.eth.getBlock("pending").gasLimit
6712390

then in the truffle.js:

module.exports = {
  networks: {
    development: {
      host: "localhost",
      port: 8545,
      gas: 6712390,
      network_id: "*" // Match any network id
    }
  }
};

Some of you guys have contracts that just don't deploy. Either because you have a mammoth one that has too big a bytecode or because you throw in the constructor.
This thread is not what you are looking for.

Of course, if you get an error on any net, it has nothing to do with the net, or the main net.

i had the same issue with either running out of gas or exceeding block gas limit (on the development-network). my contracts were big.
With truffle 4.x, the solc-optimizer got switched off by default. switching it back on solved it for me:

in truffle.js
solc: { optimizer: { enabled: true, runs: 200 } }

maybe without optimizing they exceeded the max stack-depth?...not sure, happy it works

I got an error message with gas:6700000. I changed it to 670000 and it worked.

wanderingstan added a commit to wanderingstan/Origin-demo-dapp that referenced this issue Dec 14, 2017

Turned on `solc-optimizer` in truffle.
Was getting "Exceeds block gas limit" errors locally, and this fixed it.

I think the error is too generic and misleading. That is why it works for some people and does not for some others, because the root cause is different, but the error is same. (too generic)
I blogged about my experience here : https://mandarvaze.bitbucket.io/posts/please-check-your-gas-amount-maybe-misleading.html
tl;dr : It was "code" issue (Should have been compile error IMO)

I found that my cause of the error was missing '0x' in .deploy( ) parameter
So I had to use
web3.eth.Contract(JSON.parse(filename.interface)).deploy({data:'0x' + bytecode}).send({gas: '1000000', from: accounts[0]});
