When you create a new database in an instance of SQL Server 2017, a deadlock condition may occur.
Note The deadlock condition is more likely to occur if the instance of SQL Server has many existing databases.
This issue may occur when a background system task is running that frequently looks for existing resumable indexes in all databases.
This fix is included in Cumulative Update 1 for SQL Server 2017.
