This object enables the consistency checker to log an error message whenever it detects a FIB inconsistency. With this off, inconsistencies could be silently detected and even auto-repaired without leaving any trace in the syslog, making it much harder for an admin to notice recurring FIB corruption over time. An admin debugging intermittent traffic black-holes would enable this so that the next time a checksum error or missing prefix is found, a syslog entry pinpoints exactly when and which checker caught it.
