Unreliable HTTP checks

[jacobat]

Creating an HTTP kind of health check fails every other or third request.

I have a check like:

{
  "ID": "my_app",
  "Name": "my_app",
  "Tags": [
  ],
  "Address": "192.168.42.120",
  "Port": 3000,
  "Check": {
    "HTTP": "http://192.168.42.120:3000",
    "interval": "10s",
    "timeout": "1s"
  }
}

And in my web server logs I see:

192.168.42.120 - - [30/Mar/2015:14:38:07 +0000] "GET / HTTP/1.0" 200 - 0.0011
192.168.42.120 - - [30/Mar/2015:14:38:17 +0000] "GET / HTTP/1.0" 200 - 0.0011
192.168.42.120 - - [30/Mar/2015:14:38:37 +0000] "GET / HTTP/1.0" 200 - 0.0011
192.168.42.120 - - [30/Mar/2015:14:38:57 +0000] "GET / HTTP/1.0" 200 - 0.0012

Notice the missing checks at :27 and :47.

Using the "script" kind of check works reliably and will make a request every 10 seconds.

This looks like a duplicate of #779 - I'm guessing it's the same issue.

It does indeed. I'll await the next release and report back if I still see the issue.
