Error in block freeze operation

[gunanshuCN]

My Geth network was running smoothly for nearly five weeks. Suddenly, it halted, and I found the following error in the logs:

Environment Details:

Plenty of storage space available on the VM (~75% in use).
Running Teku for the consensus layer.

Can you provide a bit more logs?

Looks like your node is in recovery mode after the unclean shutdown and somehow the chain segment to be frozen is missing.

Is it the ethereum mainnet? Or some private networks?

@gunanshuCN have you had an unclean shutdown? (e.g. docker kill or something like shutting down the computer without powering down the vm?) Could you show us your startup logs if you still use the node or have you resynced in the meantime?
