Comment 10 for bug 1591411

I would like to thank the GitLab team for their excellent work triaging this issue (and getting a patch ready). Very nice work. I tested the version of dbus in Stan Hu's PPA here:

https://launchpad.net/~stanhu/+archive/ubuntu/dbus

After updating dbus to the version in this PPA, I ran my "ssh to a container" test (which I used as a test case reproduce the bug to file this), and also on another test system that was experiencing this issue with a real-world use case.

This time, I was able to SSH into the system several thousand times, and everything worked fine.

Next I turned it up to eleven by running eight continuous-SSH scripts in a loop. In a minute or two, it fell over and went back to the 25-second delay behavior. So while the behavior is *much* improved with the dbus patch, there are still lingering issues, and I think we should consider patching systemd as well (in addition to triaging further to determine if there is larger design flaw that can be fixed separately).

I think it's worth patching dbus alone as a first step. I will test Łukasz's systemd PPA to see if that further improves things.

Thanks again to everyone in the community who helped pull together a fix!
