Alert flag status for entries forced off of the Intrusion Log

If the Intrusion Log is full of entries for which the alert flags have not been reset, a new intrusion will cause the oldest entry to drop off the list, but will not change the alert flag status for the port referenced in the dropped entry. This means that, even if an entry is forced off of the Intrusion Log, no new intrusions can be logged on the port referenced in that entry until you reset the alert flags.
