Since yesterday, we have been receiving significant amounts of error 1's when running this specific multiquery:

Once a user receives the first error 1, they are stuck in this state and will continue to get error 1's every time this query is run. One user experienced this issue for over 6 hours until the user stopped receiving error 1's
