When you execute a query for which you don't have sufficient permissions to perform operations, a memory leak occurs in the MEMOBJ_SOSNODE type object in Microsoft SQL Server 2014 or 2016.
Note The memory leak depends on how frequently the query restarts. The only way to release memory is to restart your instance of SQL Server.
