Chainlink 节点：交易未决时该怎么办？

Question

I have a chainlink node, and there are transactions that seem to be stuck. How can I fix pending outgoing confirmations?

Answer 1

Most often, you did not fund your chainlink node account with gas. Go to your configration and grab the ACCOUNT_ADDRESS and send ETH to that address.

The second most common is that you're using an outdated version of the chainlink node. Please use 0.9.4 or higher.

For pending Outgoing Confirmations:

1. You did not fund your chainlink node account with gas.
2. The ETH chain is clogged up.
3. Your MIN_OUTGOING_CONFIRMATIONS variable in your .env is too high (it gets set to a default)

If you see pending transactions at your oracle contracts address then it is likely #2. If you don't see any, it's likely #1.

If #1, you can just send some ETH to your node and it should be fine. You can find your node's address ACCOUNT_ADDRESS in the configuration page of your Chainlink GUI.

If #2 you can either:

1. You can delete the pending transactions from your database and hope everything clears up (This is an OK solution, hopefully smart contracts have a retry parameter for dealing with you data. But if your node stays stuck, then NO one will be able to get data. )

DELETE FROM job_runs WHERE status = 'pending_outgoing_confirmations';
DELETE FROM tx_attempts WHERE confirmed = 'f';

2. If you need those transactions to go through, you can rebroadcast the transactions with more ETH gas to push them through faster. This is a little trickier to do. The Chainlink nodes have a built in system to push transactions through without you having to do anything, so hopefully they will kick in.

If #3 Set or change your MIN_OUTGOING_CONFIRMATIONS and restart the node.

For Pending Incoming Confirmations:

This is likely due to network congestion or you're working on a network that doesn't have many transactions. An easy fix is to reduce the number of incoming confirmations and restart your node.

In your .env file, add or set the following:

MIN_INCOMING_CONFIRMATIONS=0
