"Unsolicited response received on idle HTTP channel starting with "0\r\n\r\n"; err=<nil>"

[PDVJAM]

I have built ipfs with this plugin, and everything works fine, I see my files in S3 bucket. But in logs I see a lot of " Unsolicited response received on idle HTTP channel starting with "0\r\n\r\n"; err=" messages. What might cause them? And how to fix? Any ideas?

@MichaelMure any ideas/thoughts?

Ultimately the cause is that something is violating the HTTP state machine. In https://github.com/golang/go/issues/19895 this happened on a HEAD request that returned a chunked-encoded body...the Go HTTP client read the head request but not the body, since HEADs don't have bodies. The leftover bytes aren't a valid HTTP message, hence the error. go-ds-s3 does issue HEAD reqs for GetSize calls, so it might be that, or something else.

If you are still having this issue, try turning on debug logging in the AWS SDK to show the HTTP reqs and responses. If server responses look fine then it is likely a bug somewhere client-side.

@aschmahmann I don't see any logs like that in our systems.
