2.5 Crash - possibly because WAN (Virgin broadband) went down?

Hi,

Woke up this morning to find that my pfsense 2.5 firewall had hung. Rebooted it and everything is fine. Looking at system.log i can see the following up until i cycled the power.

Mar 11 00:00:00 gateway php[98000]: [pfBlockerNG] Starting cron process.
Mar 11 04:05:54 gateway rc.gateway_alarm[34954]: >>> Gateway alarm: WAN_DHCP
 (Addr:x.z.x.y Alarm:1 RTT:8.315ms RTTsd:2.247ms Loss:21%)

Mar 11 04:05:55 gateway php-fpm[11794]: /rc.openvpn: Gateway, none 'available' for inet, use the first one configured. 'WAN_DHCP'
Mar 11 04:05:55 gateway php-fpm[11794]: /rc.openvpn: Gateway, none 'available' for inet6, use the first one configured. ''

Checking the config of my WAN interface in Pfsense I can see that IP4 is set for DHCP (from ISP's modem) and IP6 is set to None. So i'm not sure why at 04:05:55 its looking for inet6? And is that the cause of the crash?

Any views pls?

Thanks in advance

@yeleek , strange things are happen when you are not active. Next time, make sure your DHCP and DNS resolver services run before going to sleep ;)
