netctl/wpa_actiond - dhcdcd not adding default route

My setup is essentially a laptop that sites on my desk at work. I only use it occasionally, so I suspend between uses. When I do wake it up, it has to reconnect to the wireless but to the same SSID. However, some times it'll get a new IP address over DHCP but it won't correctly set the default route. systemctl status netctl-auto@wlp4s0.service shows

and ip route shows

$ ip route

I checked system logs for what happens immediately on wake up from suspend, and something that seems odd is the following

The thing to notice is that there are apparently two concurrent versions of dhcpcd running, on PIDs 419 and 15874. Maybe this is by design, I don't know, but they both seem to be changing the default routes at the same time, which could be a problem. Note that restarting the service always fixes my issue. It also never occurs if I visit some other location/SSID with my laptop before connecting it at work. Has anyone seen anything like this? Is there something obvious I should try to fix it, or debug it further?

Re: netctl/wpa_actiond - dhcdcd not adding default route

Most likely an eduroam problem. Check your config and open a bug report for netctl, if everything is fine. Eduroam, my immortal enemy...
