UI freezes when gateway goes down with multi-WAN
-
I found a strange behavior with multi-WAN setup.
When one of the gateways goes down, I often observe the whole pfSense web UI gets completely inaccessible (when this happened last time I just had home page open with some charts).
"Max Processes" is set to 10, which is already more than default. I'm wondering what it might be. -
This seems similar to https://redmine.pfsense.org/issues/11733, which was closed for no reason (the issue was with ONT, not LAN link, so there was no reason fro web UI to stop responding).
This apparently affects all interfaces regardless of which gateway goes down.
Right now I have WAN as Tier 1 and WAN2 as Tier 2. When WAN2 (second ISP) has packet loss, I both lose Internet connectivity using WAN and web UI becomes unresponsive.
Not always, but often, which is especially annoying during video calls.Here are the logs from the last time it happened:

Nginx error is especially concerning. That was me trying to refresh frozen page, but I was unable to do so.
