FortiAP431F is increasing memory usage

[JuanPerezLopez]

Hello everyone, I have 4 FortiAP 431F (FP431F) with firmware v7.0 build0134, the issue is that memory usage increases with and without connected users. I restart them and they start with 38% of the memory occupied, after 3 or 4 days the memory reaches 93% usage which makes browsing slow when users are connected. I have to restart it again to free up memory and the same thing happens again.

Do I have to update its firmware to a more stable version?

Thanks!

Hi JuanPerezLopez,

I checked the release notes of 7.0.7 and there is no known issue regarding memory utilization.

You can try a different firmware version, like 7.2.x or higher. If the issue still persist after that you will need to raise a case with the support team for further investigation.
