Go-ethereum: Some transactions keep being pending on rinkeby

[ligi]

I currently have a problem with rinkeby. Sometimes transactions keep stuck in pending state and never make it to the chain. Also replacing them with others and increasing gas-price does not help.
I was talking shortly with @karalabe on gitter about it and there seems to be a correlation with the hot-fix
for accepting 1wei txs

Péter Szilágyi @karalabe Jun. 23 17:16
there was a bug in the miners that made them accept 1 wei txs until now, fixed it today :stuck_out_tongue:

ligi @ligi Jun. 23 17:17
hm that might be the reason then - will investigate :wink:
and the rinkeby miners updated today?

Péter Szilágyi @karalabe Jun. 23 17:18
yup, 2 hours ago
I pushed out 1.6.6 stable into them

ligi @ligi Jun. 23 17:19
yea I think this is the point ERC-20 transfers stopped for me :wink:

Péter Szilágyi @karalabe Jun. 23 17:20
sry :grinning:

ligi @ligi Jun. 23 17:20
was also wondering because my chain-watcher does not see any other ERC-20 transfers currently
no worries - just wondering :wink:

Péter Szilágyi @karalabe Jun. 23 17:20
someone was abusing this bug btw, spamming with 1 wei txs
hence why I needed to fix asap

some more testing over the weekend: It does not only affect ERC-20 transfers - also normal ETH value transfers. It mainly happens with my main-account 0xfdf1210fc262c73d0436236a0e07be419babbbc4

https://rinkeby.etherscan.io/address/0xfdf1210fc262c73d0436236a0e07be419babbbc4

example for a stuck tx: https://rinkeby.etherscan.io/tx/0x7e3ffc00244eee6526c2cda98e5f098092c9a7fd088cfecdd1fa164c423052ca

[karalabe]

On one of my full nodes on Rinkeby, the txpool contains

    0xfdf1210fc262c73d0436236a0e07be419babbbc4: {
      121: "0x0a057a87ce9c56d7e336b417c79cf30e8d27860b: 0 wei + 73000 × 2000000000 gas",
      122: "0xe89889f3cf1e02dc6a5f61892444f20513008659: 334000000000000000 wei + 121000 × 222000000000 gas"
    }

Which would explain why it's not included. I'm wondering though why your higher priced replacement tx didn't propagate to the node. Will need to look into this closer.

[ligi]

thanks!

[karalabe]

Can you get me a raw RLP of that transaction?

[karalabe]

The odd aspect is that none of the other nodes see your transaction either, it only appears on Etherscan.

[ligi]

Unfortunately I did not save the RLP of this particular transaction. I could craft a new replacement-transaction and send you the RLP of this one if you want. It might be that I only relayed this transaction to etherscan - because I am testing other stuff currently and things are just faster when I do not start the light-client - but etherscan should still propagate them - had no issue with this method before. But I would do everything to get to the bottom of this problem ;-)

[karalabe]

Please send me an RLP here without broadcasting. Let me see what happens if I push it via my node.

[ligi]

0xf86c798509d350e60082520894e89889f3cf1e02dc6a5f61892444f205130086598805d7b144fa708000801ba01e7f6c7962cef13b3c449a57d6e6f92dc4b99ea065f558e14b8c71269e7d82a3a053853ba86ffd29339419a070b349b69923bba8aee357aeb4e4c51cb83ae2fc1c

[karalabe]

Ok, trying to push that into Etherscan gives me {"jsonrpc":"2.0","id":1,"error":{"code":-32000,"message":"replacement transaction underpriced"}}, which should be expected, since you gave me one with 4.2 gwei.

My local node accepted it and now I see the higher gas limit as peding, but it's still below the 10gwei needed for mining :P Can I haz one that it above 10 gwei please?

[karalabe]

Ah wait, it was 44, and it was indeed added to the chain.

[karalabe]

This might actually be a bug in etherscan. If you look at your account, https://rinkeby.etherscan.io/address/0xfdf1210fc262c73d0436236a0e07be419babbbc4, it still shows nonce 121 as pending, even though there is a valid transaction with nonce 121 and also 122 already imported. Perhaps that original 121 got stuck in some etherscan pipeline. Any ideas @mtbitcoin ?

[karalabe]

@mtbitcoin What version of Geth is your rinkeby explorer running? Could you send me a dump of txpool.inspect from it?

[ligi]

yea the gas-price was 42,2 gwei and I see the transaction now - hm so the problem seems to be on etherscans side? Still odd - because this was working perfectly before and I got these problems after the change to the miners. But could also mistake correlation for causation here ..-)
Thanks for looking into this anyway!

[karalabe]

Previously there was no notion with replacement transactions because everything was accepted and mined.

[mtbitcoin]

@karalabe was running one version late. Just updated to the latest. Here is the dump fro txpool.inspect https://gist.github.com/mtbitcoin/e753b4f6afbe4b8f6a8f623be71998af

[karalabe]

@ligi Could you keep playing with this setup and see if it happens again?

@mtbitcoin Any change or surfacing the eth_getRawTransaction API call (or making it possible to retrieve the raw transaction dump from the explorer)?

[ligi]

@karalabe sure thing - doing some test-runs currently

[mtbitcoin]

@karalabe Can you elaborate on "Any change or surfacing the eth_getRawTransaction API call" ?

[karalabe]

**chanCe oF

@mtbitcoin Sure. So you currently have https://rinkeby.etherscan.io/api?module=proxy&action=eth_sendRawTransaction&hex=0xf904808000831cfde080&apikey=YourApiKeyToken, where I can submit a raw transaction, and I was wondering if you could provide a similar endpoint for eth_getRawTransaction where I could get the raw form from etherscan.

Currently for some reason only etherscan saw this pending transaction and I would have liked to resubmit it from my node, but there was no way for me to retrieve the raw RLP of the transaction from your website.

[ligi]

seems to work fine so far! Just had a short moment where I thought replacing transactions might still be a problem - but it just seems that even 10gwei does not get mined - increasing it to 20gwei helped. Thanks @karalabe & @mtbitcoin for the really fast reaction - you rock! From my side this issue can be closed - will do some more testing - but I think the update of geth on etherscan solved the problem - thanks so much!!

[mtbitcoin]

@karalabe {"jsonrpc":"2.0","id":1,"error":{"code":-32601,"message":"The method eth_getRawTransaction does not exist/is not available"}}

[karalabe]

@mtbitcoin Seems to work for me > eth.getRawTransaction("0xda340a4fd46a21b40c1da5e1292e28d0aa9fc387487be99b79aa12076925a16b") "0xf8ac8203388504a817c800830105ab94aec9ecdafaf2404f824b4b7087e9e4f90c77d08280b844799cd333623664633265663766323230343666353739383666646235333161643332343130626666306265396330343164616634343530613061646430653037393764362ca06ae43876cc17ee31a51291ef92de58e4792f70dee8793f7548fa1befbba0cf31a0530348dc332f105ae8a4fb291bc689245d1cdb9b3ee625828d820ce4bd5b7a80"

@ligi I think only one miner mines 10gwei, so it takes some time.

[ligi]

closing this issue as the update of etherscan to the latest geth version seems to have fixed this problem

[reddec]

Good day all! Have the same problem (more then 5 hours in pending state)
https://rinkeby.etherscan.io/tx/0x8ea419741a5f7b31b54564d1989affce88209f894866c23f0b85eac7b01c47ce

[karalabe]

@reddec Could you please send me the raw transaction data so I could inspect it?

You should be ale to retrieve it from your own node via eth_getRawTransaction("0xc585b7aba4016613d78f96b5add29294aeeb44452116ae9bf1b6c14e38ae477b")

[karalabe]

Ah, found the error. The gas price you specified for the blocked transaction is 0.21 gwei (all other txs you made are 21 gwei). The minimum a Rinkeby miner currently accepts is 1 gwei.

[reddec]

@karalabe Thanks! Sorry

[snollidea]

Hi all! I have same problem. My tx more then 2 hours in pending state. But every 12-15 min tx time does down to zero.

[karalabe]

You have nonce 1 of your account blocked with a 20 wei gasprice
transaction. You need to replace that with a high eniugh one for miners to
process.

@karalabe Thank you!

I'm having the same issue. Any ideas?

[GeeeCoin]

@karalabe does gas price affect txn speed or is it first come first serve on Rinkeby? If there's documentation that discusses details, would love to see it.

[karalabe]

The same rules apply as on mainnet.
