Experience exact same issue with Besu + Lighthouse combo running on a server (Debian 11, no VM, no docker).

[SomerEsat]

+1 Besu + Lighthouse
Results in missed attestations periodically.

[lfinbob]

Seeing this a lot on Rocket Pool nodes. Affects all CLs. Powerful servers and small machines alike.

[risasoft]

+1 Besu/Lighthouse on RocketPool. Seems to happen every few hours.

[gamell]

Same with Besu + Lighthouse in a RP node using latest opensdk Docker image

[arbora]

+1 Besu/Lighthouse - been experiencing this since Merge, with occasional missed attestations, potentially when they happen at the same time as the issue.

[kinther]

Besu/Nimbus seeing this as well. I was synchronizing fine this morning and then suddenly it began spitting out the fork-choice-update logs. The variables within that log change with each iteration. I have restarted Besu multiple times without any change in behavior.

After restarting both Besu and Nimbus, I'm now seeing the following on start

Same problem here - Besu with Lighthouse. 1 missed attestation slot so far (slot 4701535 at block 15538896).

But VC and BN dont show any errors, Besu had the JSON error a few mins before the missed attestation.

Didnt have any issue all this while on Besu, until a few hours after the merge when the JSON streaming errors started popping up in Besu.

Restart didn't help preventing more errors. No more missed attestations yet.

From a Discord message:
Here are the cleanest Besu logs I can get for one of these instances of ERROR | JsonRpcExecutorHandler | Error streaming JSON-RPC response, with associated Lighthouse logs. Also an inclusion of a graph of rate(execution_layer_get_payload_by_block_hash_time_sum{}[5m])/rate(execution_layer_get_payload_by_block_hash_time_count{}[5m]) which a lighthouse dev thought might be informative, but which doesn't show much at the time of the error.

Note: No attestation was actually missed at this time by validator xxxxxx, but it had a possibly-related invalid head/target vote which resulted in effectively a missed attestation.

As for env details: i7 NUC with 32GB RAM and 2TB Samsung EVO 970 SSD. All metrics were well in the green at the time of the error, with no suspicious bumps of any kind.

I'm getting this error every few min:

No negative impcat on metrics or missed attestations

[siladu]

+1 Besu + Lighthouse
Results in missed attestations periodically.

@SomerEsat please can you explain how you came to the conclusion that Json RPC error leads to missed attestations please? Some users have this but without missed attestations

[siladu]

@ibootstrapper @JanKalin @ronaldjmaas @lfinbob @risasoft @gamell

Please can you confirm if you are getting frequent missed attestations and how your chains are progressing generally?
Are you seeing this error but everything else is fine?

[gamell]

No missed attestations on my side, but switched to a geth/lighthouse fallback node as precaution for now, so I only have ~10h of logs/attesting experience with this issue.

I went from 99% to 83% effectiveness pre to post Merge. No changes to setup. Software latest versions. Fully synced prior to the merge. Also, Beaconcha.in confirmed it via alerting.

I'm not sure what actual cause is, but it seems to happen when I see this (Besu):

-- Lighthouse reports a "Error during execution engine upcheck" at 00:16:02.001
-- Besu reports a "Error streaming JSON-RPC response" at 00:16:02.851

Around that time, if an attestation is scheduled, it tends to fail. Having said that, the last attestation to fail (across multiple validators) is approx. 1 hour ago from now.

Edit: Just got alerts for 2 missed attestations (1 each from 2 separate validators).

Please can you confirm if you are getting frequent missed attestations and how your chains are progressing generally? Are you seeing this error but everything else is fine?

I've personally only missed 1 attestation per validator after the merge, despite 126 JSON-RPC errors:

# docker logs rocketpool_eth1 |& grep "Error streaming JSON-RPC response" | wc -l
126

It's a fast server, Ryzen 5950X, 128GB RAM, 2x4 TB NVMe. Many other Besu users in Rocket Pool discord #support see more missed attestations or no attestations at all, especially on weaker devices.

My rated.network effectiveness seems to be still fine as well:

[terahertz5k]

I am getting missed attestations with this error and lighthouse. was not getting any before the merge. my effectiveness has dropped from 97-100% to 85-89% on two validators.

Just after the merge I had to restart besu as many others. I had one missed attestation today, but that was before the restart.

From the merge to now (3:27 CEST) I've had 257 JSON-RPC errors and 9 errors org.hyperledger.besu.ethereum.trie.MerkleTrieException: Unable to load trie node value for hash. But the trie error occured also before the merge, around once per day, whereas the JSON-RPC didn't.

Except for this error both the execution and consesus layers are following the chain in real time. HW is AMD Ryzen 5 5600G, 32GB RAM 3.2GHz and Samsung SSD 980 Pro 2TB, with load hovering a bit below 1.0, and loads of free RAM. I added JAVA_OPTS=-Xmx8g to my startup script for besu.

EDIT: the consensus layer client is Lighthouse

[realsnick]

Yes, missing many today . I'm running in a HP server 512gb ram and 4x10 cores (80 threads)

Chain is progressing, but this results in one missed attestation every few hours. Here is an example miss:

eth_getBlockByHash - Error streaming JSON-RPC response

[ronaldjmaas]

@silado Since merge I missed 13 attestations. Although I see a lot of RPC JSON related errors in both Besu and Lighthouse BN log, I do not see any errors in the Lighthouse VC. Lighthouse VC log always shows 'Successfully published attestations' regardless if attestations were missed or not.

Besu + Lighthouse clients are successfully synced to chain. No issues there.

Note before merge I only missed 1 or 2 attestations during monthly upgrade / system reboot. Node has been running rock solid for many months until today.

[adv0r]

[siladu]

We added logging and see that lighthouse (which I think most users on this issue are using) sending eth_getBlockByHash is responsible for the streaming JSON-RPC response error, at least on our canary node.

There is something odd in the Lighthouse VC logs for the published attestations that miss. Not sure if it is relevant or not:

[ahamlat]

Here some update from the team.
We find a bug in the code where all the calls that come through the engine API port (8551) are sequential. For example, especially for the pair Lighthouse/Besu, all the errors io.netty.channel.StacklessClosedChannelException on eth calls are thrown because they have to wait to some engine_newPayloadV1 call to finish its execution, and this may take more than 1 second, which is the timeout set from the CL side.
We're currently working to make ETH calls parallel to the engine API calls, even if these ETH calls are made on port 8551.

[Primea1]

Still an issue with new update
