      @tosman61 : a dns with 0.0.0.0 doesn't shock you ?
      The log also show up using a single WAN  ?
      Your are using the captive portal on LAN ?
      Are you syslogging to a syslog server (on LAN) ?

      No "help me" PM's please. Use the forum, the community will thank you.
      Edit : and where are the logs ??

            I think there is the problem, many redirects from the header…

              setup a syslogd to a server and the pfSense box is dumping the same error and not the full "too long" message
              "nginx: 2016/11/17 08:36:08 [alert] 38209#100232: send() failed (40: Message too long)"

              What happens for me is I get many of these messages then the system will not allow gui access and affects the openvpn sessions, but other traffic works as normal.

              I'm running a SG-8860 box with the lastest version, no additional packages loaded, one internet connection, 4 subnets, 20 IPSecs and an average of 5 vpn's.

              I need to know what these too log messages are to see what is causing the problem.

                      Same trouble with my pfsense after upgrade to 2.3.2 pi1, coming from pfsense 2.2.x
                      I didn't installed any Captive portal.
                      This issue looks related to the web interface, even if i can't be 100% sure.
                      I tried to remove all widgets from dashboard, switch from http to https, and taking a look from shell with "tail -f /var/log/nginx-error.log", an alert entry appears a couple times per minutes, instead once per second as before.

                                Did you try to change your old redirect URL "http%3A%2F%2F172.16.0.1%2F" == "http://172.16.0.1/"
                                to "http://www.google.com" instead of changing the source ?

                                What pfSense version ? - is it patched or modified ?

                                  The same here.
                                  After re-applying the squid settings it stopped to logs the errors, but after 2 or 3 days (depends on load) it reappears

                                          Aug 28 10:22:38	pfsense.localdomain		nginx: 2019/08/28 10:22:38 [alert] 54908#100145: send() failed (40: Message too long)

                                          I experienced this also in latest pfsense right now. my captive portal disconnects .I hope there is a fix for this.
