      Since the update to pfSense 2.2 I've got a lot of those error in my kernel log:

      kernel: sonewconn: pcb 0xfffff80003b03310: Listen queue overflow: 8 already in queue awaiting acceptance (5 occurrences)

      The logs always have the same pcb address. I've also looked for this address in netstat but I didn't find anything. I've also disables OpenVPN for some time but the logs are still appearing. Does anyone have an idea what could cause this problem?

        I've just found out that the miniupnpd is causing these errors. If I disable the upnp service the error logs do not appear any more. When upnp ist active I also get error in the "Routing daemon log entries":

        miniupnpd[49093]: accept(http): Software caused connection abort

        What could cause this problem and how can I solve this?

        Edit: I now found the source of the problem. The problem was the DLNA server on my QNAP nas. It sent a lot of upnp spam to the firewall which rejected most of the requests. I've now disabled the DLNA server completeley and I'am now using Twonky server instead.

          I am having this issue now after upgrading to 2.2.2 - The only thing i am running is OpenVPN…
          Have no clue why it appears.
