> Project: Camel
> Issue Type: Bug
> Components: camel-netty4-http
> Affects Versions: 2.18.3
> Reporter: Valentin Tsvetkov
> Priority: Major
>
> I try to make simple proxy application with netty4-http component to transfer
> http request with large content.
> Example
>
> from(String.format("netty4-http:http://0.0.0.0:%d?httpMethodRestrict=GET,HEAD,POST,PUT,DELETE,TRACE,OPTIONS,CONNECT,PATCH&chunkedMaxContentLength=100000000&disableStreamCache=true";,
> 8081))
>
> .toD("netty4-http:http://somehost:8080/?bridgeEndpoint=true&throwExceptionOnFailure=false&useRelativePath=true";).end();
> So if i use &disableStreamCache=true option then i get
> [Camel Thread #3 - NettyClientTCPWorker] WARN
> io.netty.util.concurrent.DefaultPromise - An exception was thrown by
> org.apache.camel.component.netty4.NettyProducer$ChannelConnectedListener.operationComplete()

> at io.netty.util.ReferenceCountUtil.release(ReferenceCountUtil.java:84)
> If i does not use &disableStreamCache=true, all works fine. But for large
> content i get heap space error.
