Since going to 2.5.1 I loose WAN2 every 12 hours

[pclausen]

I have noticed that since going to 2.5, WAN2 drops every 12 hours. The odd thing is that WAN2 still shows traffic:

If I then run speedtest, the traffic goes to WAN1:

I can reset WAN2 by going to Interfaces and just hit save. After doing that and running speedtest again, I get traffic across both WAN connections:

Looking at the gateway logs for the last 24 hours, I see the following:

The entries @ 06:46:05 yesterday and @ 06:39:03 this morning is from when I reset WAN2.

Filtering on just the Alarm latency entries, I get this:

So it looks like my ISP does some sort of "reset" on WAN2 every 12 hours like clockwork, and pfSense, since version 2.5, is never able to recover.

Any thoughts on how to fix this?
