        Restarting container will make everything behave as "normal", querying the default NuGet feed in the UI takes approx 2 secs.

          This sounds like it's network-traffic related, and likely the server is getting overwhelmed...

          See How to Prevent Server Overload in ProGet to learn more.

            @atripp If it would be a network related problem, wouldn't this error go away when the load lightens up? As we experience it there isn't much load on the server and when it starts to timeout on connections it won't recover until we restart the container. And when we do it justs work again.

            We have added some monitoring with Prometheus (advisor for Docker and node_exporter for the host) and those reports don't show any significant load/traffic on the server when this happens.

              @atripp Is there an easy way to see the number of ProGet requests?

              I have tested to run tcpdump to find out some network-related information, but it's not that easy to determine how many simultaneous calls it actually serves.

                I'm not aware of how to do it; ProGet does not provide monitoring at this network level. Do you have an ngix proxy in front of it? We've heard that's very important, and it can help deal with some other mono bugs around not closing keep-alive connections quickly. And and also lets you have SSL as well.

                  @atripp Yes, we are running nginx. But I will look into the keep-alive connections and see if that can give some hint on the problem.

                    It is still an issue, tested to update the host Ubuntu to the latest 18.04 packages to see if something gets better from that (including a later docker).

                      Hi @patchlings,

                      Have you enabled the nginx HTTP Stub Status module on your nginx proxy? I would be interested to see the number of open and waiting connections. Although this article is old, nginx: See Active connections / Connections Per Seconds seems to show a pretty easy configuration to see this status. I would be curious to see these counts when the problem exists. Would you be able to enable this and post the counts when everything is working and when it is not?

                      Thanks,
                      Rich

                      Products Engineer, Inedo

                        @rhessinger I will look into that!

                        Meanwhile, I tested to run "kill -QUIT $MONO_PID" to get some thread dumps from the mono process when the problem appears.

                          Hi @patchlings ,

                          I was doing some Docker research around this issue. Something I found Docker users complaining about was an issue with the total number of available connections on the host. It seems that the more containers running on a host (especially with database containers on it), the connection count can get spread a bit thin under load. Have you tried increasing the max number of connections? Here is a StackOverflow about increasing them Increasing the maximum number of TCP/IP connections in Linux.

                          Also, how many connectors do you have on your NuGet feed?

                          Thanks,
                          Rich

                          Products Engineer, Inedo

                            @rhessinger We have enabled the stub_status for Nginx, when the problem appeared just now the status showed the following page:

                            Active connections: 15
                            server accepts handled requests

                            Reading: 0 Writing: 2 Waiting: 13

                            We have some network connection monitoring with prometheus for the host and they show nothing specific (see attached image)connections.png

                              @rhessinger said in Connector errors, timeout, restart needed.:

                              Also, how many connectors do you have on your NuGet feed?

                              Sorry, I missed this question... We have four connectors (but only uses three of them): connectors.png

                              And when I looked that up I noticed that the one we don't use was marked with error, removed it.

                                Hi @patchlings,

                                Do these connector errors happen on all your feeds? Or just NuGet?

                                Thanks,

                                    Thank you very much for the information. I'm researching the issue more on our side. I may send over some more questions your way while I'm working on this.

                                    Thanks,

                                      Now it's seems flaky again:

                                        One interesting observation is that when the system "freezes" there seems to be no traffic at all (12:30):

                                          Performing strace on the mono process gives a lot of:

                                          [pid 26706] recvfrom(39, "", 8, 0, NULL, NULL) = 0
                                          [pid 26706] recvfrom(39, "", 8, 0, NULL, NULL) = 0
                                          [pid 26706] recvfrom(39, "", 8, 0, NULL, NULL) = 0
                                          [pid 26706] recvfrom(39, "", 8, 0, NULL, NULL) = 0
                                          [pid 26706] recvfrom(39, "", 8, 0, NULL, NULL) = 0
                                          [pid 26706] recvfrom(39, "", 8, 0, NULL, NULL) = 0
                                          [pid 26706] recvfrom(39, "", 8, 0, NULL, NULL) = 0
                                          

                                          Then I found this: https://stackoverflow.com/questions/24000534/tracing-socket-file-descriptor-back-to-bound-address

                                          So the next step will be to see if I can find out which socket that is actually appearing in the strace.

                                            Hi @patchlings ,

                                            Thanks for all this information. Would you be able to get me an open thread count for when everything is running fine and when things are not? You should be able to find it by running sudo ps huH p <PID_OF_MONO_PROCESS> | wc -l. Also, are you running these commands inside the docker image? Or on the host?

                                            Thanks,
                                            Rich
