“org.teiid.net.socket.SingleInstanceCommunicationException” when querying table in EDS Designer

Issue

• First when we tried to Preview the Orders table we received a one line “org.teiid.net.socket.SingleInstanceCommunicationException” with nothing in the Designer or server log, so then I deployed and execute the vdb instead, hoping for better logging. When executing the same query "select * from base_view2.orders" the Designer results show the same message "org.teiid.net.socket.SingleInstanceCommunicationException” but now in the server log I see it running the query, but after the second batch (512 rows) you can see the query being cancelled. The user did not cancel this query, what would be a reason for the server cancelling the query?
