@rhessinger Ok, then I understand. We will look into our options then. Depending on Mono fixing this seems like a bad solution as it seems to have appeared for quite some time.
Thanks for all your help!
What is the timeline of your Mono to .NET 5 conversion?
Hi @rhessinger
Ok, the issue you found sounds interesting, but it seems to be more connected to the other problem we have: https://forums.inedo.com/topic/2887/proget-in-docker-linux-hanging-after-using-all-memory/6
And we are currently already restarting the docker container once a day to make sure that we don't run out of memory.
And looking into the memory graphs it looks like we experience the connection issue even if the memory consumption looks ok (Green bars = scheduled restarts, red bars = connector problems, yellow graph = available memory, green graph = free memory):

Now it misbehaves...

Accessing feeds/default will show a "There was an error with a connector: The operation has timed out." All other feeds work as expected.

strace doesn't show anything obvious.
Restart docker container and now the /feed/default shows no problem. nginx status:

@rhessinger I will do that.
One note, it seems that running on debug logging level makes it a little more unstable. We are back to normal "warning" now and now it seems to be back at our regular "once a day" frequency. With debug it felt like 5 times a day.
@rhessinger Hi, if I run it on the host (or in the actual container) it seems to vary between 25-45, haven't seem anything different between when it behaves bad:
ubuntu@proget:/opt/provision/additional$ sudo ps huH p 12436 | wc -l
29
ubuntu@proget:/opt/provision/additional$ sudo ps huH p 12436 | wc -l
44
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.
One interesting observation is that when the system "freezes" there seems to be no traffic at all (12:30):
Now it's seems flaky again:

@rhessinger 99% NuGet connector errors.
@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): 
And when I looked that up I noticed that the one we don't use was marked with error, removed it.
@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

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

Running Execution Dispatcher...
Is there a way to attach a complete log file? this forum will only allow 32000 chars :-)
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).
@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.
We run prometheus to monitor our servers and cadvisor to export docker information to prometheus. It would be very useful if ProGet could export some sort of statistics to better monitor the load on the servers and maybe indicate the actual load and when you should upgrade to other licenses.
UPDATE in 2023 - see Inedo Products and Prometheus support to learn more about how to integrate our products together
@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.
Looking at the mono process it grows to more than 2 GB Resident memory on one day. Is there any number to compare this to?
@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.
Restarting container will make everything behave as "normal", querying the default NuGet feed in the UI takes approx 2 secs.
