You need to call `Loop#stop` before `server.close`.

I think adding `nil` check fixes `attach` related error. This assumes passing `nil` to loop argument doesn't happen on normal situations. https://github.com/tarcieri/cool.io/blob/5446a5e44f508ce1589a33e7ae61464530f857c2/ext/cool.io/watcher.h#L13

For `detach` related error, we need to check when this error happens. https://github.com/tarcieri/cool.io/blob/5446a5e44f508ce1589a33e7ae61464530f857c2/ext/cool.io/watcher.h#L31 or https://github.com/tarcieri/cool.io/blob/5446a5e44f508ce1589a33e7ae61464530f857c2/ext/cool.io/watcher.h#L36

@tarcieri Thanks for the link! @taichi Please check nio4r when you start to implement. It is very helpful :)

Ahhh, sorry for the late. I will check your code.

@jacob-carlborg Yes, the problem is no output. The content of generated .d file is only 'extern(C):'. I didn't know the pre-compiled binary. I tried the pre-compiled binary for Mac, it...

Yes, other test_files and C header too. I will try updated README process later.

@triha74 Do you use same config with this issue? The problme of this issue is using invalid config for `message`. They use "format json" in `in_beats` but their beats send...

@TeunRoefs Which problem happens on your environment? Shutdown is blocked or connection handling is not recovered after error? fluentd v1.x and beats plugin v1.x seems to not have former problem...

@TeunRoefs I see. To debug the problem, I want to reproduce this bad fd problem but hard to it in my laptop. So I want to know how to reproduce...
