btcd has stopped updating the block database for 36 hours.

This is a newbie question. I just started running btcsuite/btcd. After the blockchain takes a few days to initialize, it doesn’t seem to write any more new blocks. btcctl getblockcount reports 828835, about 36 hours behind today (2024-02-05).

The logs seem to show valid activity.

Checking the database file directory also reveals the problem.

Does anyone know what is causing this problem? Is my server down due to a dead-end fork? Can I revert the chain to the “last good block”?
