Oleg Kalnichevski commented on HTTPCLIENT-2152:
-----------------------------------------------
[~Acabanillas] I think I know what the problem is. Essentially it appears the
automatic asyc request re-execution in its present form is broken. As a
temporary work-around I recommend using a noop `HttpRequestRetryStrategy`
implementation that always returns false from `#retryRequest`
I am working on a proper fix for the defect.

> I am using async http client for real time bidding project in a cluster of
> servers. Each server execute around 6K request per second and sometimes each
> server restarted becase I/O reactor is shutdown. It seems that there is a
> race condition in the code that produces this behavior.
> It seems that the race condition appears between this method:
> {{org.apache.hc.client5.http.impl.async.AsyncConnectExec$1.completed()}}
> and this method:
> {{org.apache.hc.client5.http.impl.nio.PoolingAsyncClientConnectionManager$InternalConnectionEndpoint.setSocketTimeout()}}
> because in the first method the endpoint is connected but in the second one
> this code fails:
>
> {code:java}
> ManagedHttpClientConnection getValidatedConnection() {
> final ManagedHttpClientConnection conn = getConnection();
> Asserts.check(conn.isOpen(), "Endpoint is not connected");
> return conn;
> }{code}
