Hi,
I got an error while trying to run optimize on stardog 5.1.0.
This was from a disk based copy of the production database which was copied by putting the stardog database offline, copying over the entire directory and then putting the databse back online.

I’m going to do some tests to see if there is any data loss.
Cheers,
