However, after running for over an hour , the optimize fails stating there
is a duplicate entry in the table.
We have now spent 2 days using various methods but we are unable to find
any duplicates in the primary key and also nothing on the unique key fields.
Any idea on why optimize

is a duplicate entry in the table.

You can combine the two queries you have in option 3 (you'll need to

That's assuming that there is a unique identifier field, like an auto

you need to run the query multiple times until it returns no affected
