15.4(2)S

Description (partial)

For some FNF monitors, including ezPM monitors, if flows cache is full during metric collection,
The exported metrics results might be  incomplete.
i.e. some packets might fail to be counted in the exported FNF record, although packet did match the given flow.

This will be fixed in 3.13 only, although it is relevant for previous versions as well.
Since it's a delicate fix, and not known impact from customer so far, issue won't be fixed in previous versions.

Symptom:
incomplete metrics in exported FNF records

Conditions:
Specific monitors, ex. ezPM monitors.
Flow cache is full, and matching packets keep receving.
