Oleg Kalnichevski commented on HTTPCLIENT-2230:
-----------------------------------------------
I am not sure what you expect us to do here. There can be all sorts of reasons
for an I/O reactor to be in the shutdown state such as termination by the user
or due to an internal error. However in the latter case one should get a log
entry at ERROR priority.
I will have to close this issue as invalid without a reliable reproducer.

> We have no idea why this error accures or what is causing it.
> The only major diffference between our version was that in the previus
> version with httpclient 4.x, we consumed the response:
> httpclient 4.x code:
> {code:java}
> @override
> public void completed(HttpResponse response) {
> // some code ...
> EntityUtils.consume(response.getEntity());
> }{code}
> but now we use `SimpleHttpResponse` instead of `HttpResponse` and
> `getEntity()` is not a function of `SimpleHttpResponse`, so we removed this
> code.
> So my question is, why the error above hppends? can it be related to the fact
> that we do not consume the response? and if so - why is it related? when do
> you need to use `consume()`?
