@soporteseguridad, The Dataplane rising to a new utilization percentage really shouldn't be a huge concern, esspecially since you aren't stressing the dataplane CPU at all. With that being said however this is what I would look at. 1) Is your session utilization the same as it usually is, or has that increased overall since you noticed the uptick? 2) The Dataplane is where the majority of the work happens. Have you enabled additional signatures or setup SSL decryption or anything like that, as these would logically cause the Dataplane to show higher than it did without. 3) run show running resource-monitor ingress-backlogs and locate the top five sessions that are utilizing a larger packet buffer and post the output.
