The server ends a database update transaction for the specified session because the file space identified by the client for the transaction does not exist.
This action usually occurs when a client is operating on a file space that is currently being deleted as a result of an administrative command or client action. The server ends the specified session and server operation continues.
Use the QUERY PROCESS command to monitor and wait for any file space deletion processes to complete, or cancel the process if you do not want to delete the file space. Try the client action again after this action has been taken.
