The block it is trying to insert again is at height 12846906.

Restarting fixed this, so the most likely cause is that the queue between the query thread and db thread somehow maintained the block after it was already inserted.

Can we just add conflict resolution to ignore duplicates at the DB level?

That's not fixing the problem. There is a bug somewhere since we should never be trying to insert the same thing twice. And patching the symptom is not the way.

I believe we should do both.

Address the underlying concurrency issue and ignore the duplicates with an error.

I can create another task for the ignores duplicates?
