State Transition Failed: Seek with txNum=92295 but Data Before txNum=2821875000 is Not Available

In this article, we will explore a common issue encountered while using Erigon and Blockbook for Ethereum synchronization. The error message "state transition failed: seek with txNum=92295 but data before txNum=2821875000 is not available" indicates a problem with the state transition process, specifically when seeking a transaction with a specific number (txNum) but finding that the data before a certain number (2821875000) is not available. We will delve into the possible causes of this issue and provide solutions to resolve it.

To begin with, let's take a look at the versions of Erigon and Blockbook being used:

backend-ethereum_3.0.2-satoshilabs-1_amd64.deb
blockbook-ethereum_0.5.0_amd64.deb

These versions are the latest available at the time of writing.

Next, we will examine the Erigon sync status:

root@ip-10-0-104-40:~# curl -s -X POST http://127.0.0.1:8136   -H "Content-Type: application/json"   --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}'
{"jsonrpc":"2.0","id":1,"result":false}

root@ip-10-0-104-40:~# curl -s -X POST http://127.0.0.1:8136   -H "Content-Type: application/json"   --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
{"jsonrpc":"2.0","id":1,"result":"0x1551433"}

As we can see, Erigon is not currently syncing, and the block number is 0x1551433.

Now, let's take a look at the Erigon configuration:

ExecStart=/bin/sh -c '/opt/coins/nodes/ethereum/erigon --chain mainnet --snap.keepblocks --db.pagesize=16kb --db.size.limit 15TB --externalcl  --prune.mode full --nat none --datadir /opt/coins/data/ethereum/backend/erigon --port 38336 --ws --ws.port 8036 --http --http.port 8136 --http.addr 0.0.0.0 --http.corsdomain "*" --http.vhosts "*" --http.api "eth,net,web3,debug,txpool" --authrpc.port 8536 --log.dir.path /opt/coins/data/ethereum/backend --log.dir.prefix ethereum --txpool.globalslots 65536 --txpool.globalqueue 16384 --metrics --metrics.addr 127.0.0.1 --metrics.port 6060'

This configuration is the default configuration for Erigon.

Finally, let's examine the Blockbook start log after a few blocks:

I0426 14:21:53.729252 1120812 sync.go:497] connecting block 46000 0x1b606a41c01ae8a87784421948384b18ff8caeae35b340dfdaa6e6f9100f8a, elapsed 408.538973ms {txAddressesHit:0 txAddressesMiss:0 balancesHit:0 balancesMiss:0}

Retrying...

As we can see, the error message indicates that the state transition failed due to a seek with txNum=92295 but data before txNum=2821875000 is not available.

There are several possible causes for this issue:

  1. Data Corruption: The data in the Erigon database may be corrupted, leading to the state transition failure.
  2. Inconsistent Data: The data in the Erigon database may be inconsistent, leading to the state transition failure.
  3. Insufficient Resources: The system may not have sufficient resources (e.g., memory, disk space) to handle the synchronization process.
  4. Configuration Issues: The Erigon configuration may be incorrect, leading to the state transition failure.

To resolve this issue, you can try the following solutions:

  1. Restart Erigon: Restart the Erigon service to see if it resolves the issue.
  2. Check Data Integrity: Check the integrity of the data in the Erigon database to ensure that it is not corrupted.
  3. Increase Resources: Increase the resources (e.g., memory, disk space) available to the system to handle the synchronization process.
  4. Adjust Configuration: Adjust the Erigon configuration to ensure that it is correct and suitable for the system.

In conclusion, the "state transition failed: seek with txNum=92295 but data before txNum=2821875000 is not available" error message indicates a problem with the state transition process in Erigon. The possible causes of this issue include data corruption, inconsistent data, insufficient resources, and configuration issues. To resolve this issue, you can try restarting Erigon, checking data integrity, increasing resources, and adjusting the configuration.

Based on the analysis, we recommend the following:

  1. Regularly Back Up Data: Regularly back up the data in the Erigon database to ensure that it is safe and can be recovered in case of data corruption or loss.
  2. Monitor System Resources: Monitor the system resources (e.g., memory, disk space) to that they are sufficient to handle the synchronization process.
  3. Adjust Configuration: Adjust the Erigon configuration to ensure that it is correct and suitable for the system.
  4. Keep Erigon Up to Date: Keep Erigon up to date with the latest version to ensure that you have the latest features and bug fixes.
