OP-node stops syncing l2_finalized blocks

[AlbertMakhortov]

Bug Description At some point node just stops updating l2_finalized block (but continuing to sync unsafe l2 blocks) Restart of the node helps, but after the restart node starts walking back process, which can take a lot of time, depending on how long l2 finalized block havent been updated (sometimes week a longer)

Steps to Reproduce There is no steps to reproduce, it just happens randomly on different nodes

Expected behavior l2_finalized blocks are syncing in batches with time interval of 15-25 minutes

Environment Information:

• Operating System: docker-container
• Package Version op-node 1.7.3

Configurations: --l1BeaconUrl=http://nimbus:5052 --l1RpcUrl=http://geth:8545 --legacyRpcUrl=http://optimism-mainnet-legacy:8545 --sequencerUrl=https://mainnet-sequencer.optimism.io --l2=ws://localhost:8551 --l2.jwt-secret=secret --network=mainnet --rpc.addr=0.0.0.0 --rpc.port=9545

Logs: Logs and/or error messages that help illustrate the issue.

Additional context Add any other context about the problem here.

This impacts us pretty often

[iavl]

Sometimes such logs will be output for a long time, up to 25 minutes, l2_safe is growing continuously, but l2_unsafe is not growing. It seems that the block has stopped synchronizing during this period.

Facing the same issue. :(

[thinkAfCod]

Could provide more context information? Like Latest/finalized block height or other else.

Seems like issue was fixed in develop here - https://github.com/ethereum-optimism/optimism/pull/10210

The issue failed to fetch blobs: failed to get blob sidecars for L1BlockRef will be fixed in op-node v1.7.4. For the moment you can increase the verifier conf depth to reduce the frequency of this issue. If a node runs into this issue, you will need to restart it until you have upgraded to 1.7.4

I still have this problem after upgrading to 1.7.4

@COLUD4 could you open a new issue with logs + exact versions you are running?
