One Answer

This is an error caused on a smart contract when trying to emplace a table entry that already exists, so if you see this error but otherwise you appear to be reading and syncing blocks, then you can ignore the error entirely as it has nothing to do with you.

You can turn off the output from smart contracts by setting contracts-console and http-verbose-errors to false.
