The import population for database %1!s! (id: %2!s!), catalog %3!s! (id: %4!s!) is being cancelled because of a fatal error ('%5!s!'). Fix the errors that are logged in the full-text crawl log. Then resume the import either by detaching the database and re-attaching it, or by taking the database offline and bringing it back online. If the error is not recoverable, rebuild the full-text catalog.
