Agent module is logging error here https://github.com/DataDog/datadog-agent/blob/78ca7aad3407f9202fc0ae3f81623907a9e32691/pkg/util/hostname/validate/validate.go#L40
I don't see a need to track it.

@crobert-1 Could you help us with the best way to deal with this? (e.g. is there a template for tracking issues?)

I don't see a need to track it.

We aim to have no leaks at all in the Collector, this should be tracked and eventually fixed in the Agent.

Please add frequency and information to this issue: cihub/seelog#182

Also, please add a reference in this file to that issue so that we have future context for why this ignore is necessary.

Since this goroutine is started during a dependency's init(), there's nothing we can do if we need to import the package that depends on it. It's okay to ignore for now.
