Occurs during internal synchronization of the Extended Events timer. Therefore, referential integrity may not be accurate after any rows or pages are deallocated because foreign key constraints are not checked or maintained as part of this repair operation. Because the Resource database is modifiable only in single-user mode, the DBCC CHECKDB command can't be run on it directly. Full-featured version of SQL Server software that allows developers to cost-effectively build, test and demonstrate applications based on SQL Server software.
