After a "while" we need to restart dnsdock again

We currently have a weird bug. We can't connect to any container via DNS unless we restart dnsdock. After a "while" we need to restart dnsdock again.

We don't have trouble in our VM (Mac) / Barge setup.
We're also using this dnsdock as a resolver on our staging env, which runs each project in containers (docker-compose config per project). And that's where we see this issue. I can't find anything in the dnsdock container logs.

This way we can, for example, login with ssh and connect to a mysql container by it's dns dock alias.
This works fine, but we need to restart dnsdock after a few hours.

Thx @ailispaw I'll investigate further and post my findings here.

@jverdeyen Thanks.
BTW, if you have the problem with the original tonistiigi/dnsdock, you had better open an issue there.

When connecting to Docker over TCP, there is the possibility of the events stream connection dropping while dnsdock continues to run.

I'm not sure, but it may happen.

I guess that It may be useful to adjust TTL.

For a workaround now, you can set a cron script to check and restart the dnsdock container.
