This seems to be occurring across all instance types and is not specific to a specific image (which is good news).

I had a similar issue, but for me it was because I updated the image causing the original container to resolv to an unnamed image hence resulting in not being able to resolve that container which got it's image updated.
So to check whether you have the same image run docker ps and make sure that in the image column the image actually has a name instead of a hex code. If the original image name can't be seen in docker ps command then this may be the reason.

@samos123: You are talking about #43. This ticket seems something else.
I have the same issue. Resolving just stops. If I restart skydock container (docker restart skydock) it works again. I am not sure why this happens.

What's so special about the 20 hours?

In my case is not 20 hours, but few hours. What is interesting is that this was working for few months now and now it started failing every few hours (after restart).
from skydock.
So what changed?

Nothing. That's the problem. And there are no logs.

Those should be relatively easy to add though.

So, how should I debug this?
from skydock.
Sprinkle the code with some logging and hope it will tell you something.
But skydock also still uses skydns1, which is becoming a bit annoying as
skydns2 has been out for some time.

SkyDNS works well. I don't have to restart it. Just SkyDock.

Ah. OK. That narrows it down a bit, so yeah, I don't know anything better
than more logging at this point...

we have the same issue... some indeterminate time, approx between 2 and 24 hours, skydock just dies...

Has there been anything learned regarding this? I'm finding that I have the same issue; I constantly have to restart my containers to get this to work.

I started using https://github.com/blalor/docker-hosts instead.

Just to pull a shameless self plug I recently put together https://github.com/asbjornenge/rainbow-dock 🌈 🚀

We migrated away from SkyDock, but one theory we had was that putting a laptop to sleep would skew the clocks enough for this issue to occur. using a tool like sleep watcher helped us keep clocks aligned after wakeup. It's a little brute force but did help us.
