While interrogating the table information for our database, I notice that
some tables (i.e. gui_config, vm_mailbox, vm_message) have duplicate
entries. Does anybody know why this would occur and is it a problem?
Attached are appropriate outputs. Queries on the tables which are duplicated
in the entries appear to work normally.
We are running version 7.2.1
