I have been trying different Jetty client versions for my http client and I
have been hitting some problems with high load (several thousands requests per
minutes). I use 2 client selectors (setSelectors), 16384 as setInputBufferSize.
Same number as setRequestBufferSize, setResponseBufferSize. 2024 as
setMaxConnectionsPerDestination. setConnectBlocking set to true. For response I
use BufferingResponseListener with 8388608 as param in constructor (8 MB).
The problems are:9.3.9.v20160517:AsynchronousCloseException2016-11-26

9.3.14.v20161028 - AsynchronousCloseException
Do you have any advice why my clients gets those GO_AWAY message leading to
AsynchronousCloseException? This is the main issue. It doesn't happen all the
time but still a substantial number of requests Maxim
