When errors with a severity level greater than 16 occur, inform the System Administrator. The System Administrator should monitor all errors that generate severity levels of 17 through 26, and is responsible for resolving these errors and tracking their frequency. To assist the System Administrator in resolving problems, print out a hard copy of the error log, which contains the stack trace from any fatal error.
Messages with a severity greater than 16, show severity 16 when the error is raised by dbcc checktable or dbcc checkalloc. This ensures that checks continue with the next object.
