      Hello.
      I updated my APU Board to pfSense 2.5.1.
      On the start page i have a box showing the openVPN connections. I use two openVPN servers. On both there are connected clients. VPN is working, but on the second server the clients are not listed. The log (openVPN) says "Error: poll: too many I/O wait events".

      What could be the reason?

              @rbt said in too many I/O wait events:

              check the concurrent connections limit

              This works. Value was 1, with 2 i can see the connection. But why?

                Like OpenVPN needs a 'command channel' and a 'data channel' ? ;)

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

                  Ok, but that also means that two clients could then connect?

                    I'm using the OpenVPN server just as access for myself for remote administration.
                    So, multiple connections, for me, is a rare thing.

                    Still, I've set :

                    be7e33ae-4fa9-4c02-b4c0-ff20980e0612-image.png

                    because : why not.

                    I guess (OpenVPN doc should explain more), as soon as a 'client' tries to connect, a 'slot' is allocated.
                    If you have many 'clients' that try, and these are just scripted scanners looking for less protected (NON TLS) VPN access, slots can allocated fast.
                    Again : I guess.

                    I've not (never) seen "I/O wait events" in my OpenVPN logs.
                    I'm using two OpenVPN servers , port 1194 and port 1195. Both are completely separated, and work fine both. Both servers use TLS, and no user+pasword.
