Found the problem here, someone had created on insert and on update
triggers on this table that were interferring with the process.
This logic works wonderfully when you need sequence numbers that are also
transaction safe. The key is you need a unique index on all the columns
involved.
I think
you get a duplicate
key entry for an attempt to insert 1000 again.

There's a duplicate key on the audit table, 18699. Delete it and restart
slave (start slave). Check slave status again, might be more rows in there
duplicated.
You might want to compare the row to master to ensure it's a duplicate
