I recently started noticing that one of the WAN circuits in my dual WAN setup regularly goes down with a dpinger error. I have started noticing this after upgrading to Opnsense 24.1 and enabling IPv6 on the interface that is failing. Looking at the logs for Gateways I see these constantly

2024-04-13T13:26:42-05:00 Notice dpinger Reloaded gateway watcher configuration on SIGHUP
This error comes immediately after gateway watcher is reloaded. Not sure why SIGHUP is being generated when there is no change in the firewall or reboots. This happens only on one of the gateways (primary)
