      Hey All

      24.11-RELEASE (amd64)
      built on Fri Nov 22 15:34:00 AEDT 2024
      FreeBSD 15.0-CURRENT

      I'm getting the below error in system logs and am wondering the best way to resolve

      sonewconn: pcb 0xfffff8002753dd00 (local:/var/etc/openvpn/server1/sock): Listen queue overflow: 2 already in queue awaiting acceptance (1 occurrences), euid 0, rgid 0, jail 0

        Increasing the tunable 'kern.ipc.somaxconn' might help, but its possible OpenVPN internally has a much lower queue limit.

        pfSense CE 2.8.0

          i added 'kern.ipc.somaxconn' in system tunables and set it to 2048 however I'm still seeing the error

          Can you clarify what you mean about the OpenVPN lower queue limit and how that mioght be raised ?
