Was the column added recently?

Are you opening a new database connection when running the insert SQL?

Are you sure that the insert is actually doing anything? Are you seeing the new row?

Given that you are running 7x24 and the problem doesn't appear after a backup/restore (which is also effectively an engine restart), it seems likely that you are modifying the table structure with active connections. Those active connections are not aware of the table change...
