Balance 380 freeze after several logs "Multiple WAN health status changes"

Hi everyone,
I have an environment with a 2x Balance 380 with HA in my HQ and 2x Balance 310 with HA in my second site.
I use speedfusion to connect both sites and everything is working fine.
Recently I updated the firmware to 6.2.2 in both pep.

My problem is that every week my Balance 380 freeze the web portal and disconnect pepvpn after several log “Multiple WAN health status changes”, the connections are ok but I receive a lot of logs like that.
To resolve the problem I reboot the Balance 380 physically and everything goes fine.

Anyone have something like that?
