Constant growth of sessions in ssl/tls inspection widget

Hi,

Since last reboot I've been seeing constant growth of firewall sessions showing at the widget, at the same time, there's almost no traffic being passed on XG.

On the first picture is showing over 24.000 sessions over the last 5 minutes.

Is there any other way I can check the amount of sessions there's currently on XG? (besides on "Current Activities")

 

Thanks,
