Severity: 3-Major


By default, ASM Policy Builder is saving all its internal statistics to disk, once a day. This process can last few minutes and during this time the Policy Builder does not handle any traffic events


minor impact on the learning suggestions, some events can be ignored during the data saving time.


This is noticed only if ASM has significantly large number of entities in its policies. The frequency of this event is once a day by default.


It is recommanded to set the data saving time, to an hour of low activity.
