Unable to sync to head #138
Description
Hello 👋
I've tried Discord and other channels but cannot find the help I need so I am resorting to opening this issue.
I have been running a Reth Flashblocks node from a snapshot for ~2 weeks and doesn't seem to be able to catch up to the chain head. It appears to complete the header/bodies for a block 2-4hrs old, but by the time it finishes all the stages its ~48hrs behind.
About 1 week ago I increased the resource usage by adjusting the stages config. Generally a 10x increase has been applied as it was previously only using ~10% of available resources.
Please let me know if I can provide any other diagnostics. Any feedback or recommendations would be greatly appreciated 🙏

Not much insight here, just a lot of noise. No errors/warnings.
This appears on every new block which I believe is expected until it has synced fully:
