Hi, When I debug this unit test https://gist.github.com/cmoulliard/123261f7ac2a9d5c719c, the Camel Netty4 HTTP Endpoint is well created with the param "maximumPoolSize=2"
main TRACE [org.apache.camel.impl.DefaultComponent] - Creating endpoint uri=[netty4-http://http://localhost:26025/echo?maximumPoolSize=2], path=[ http://localhost:26025/echo], parameters=[{maximumPoolSize=2}] but the number of threads reported by Netty is still bigger than 2 Camel (camel-1) thread #4 - NettyEventExecutorGroup INFO [route1] - >> Thread name : Camel (camel-1) thread #4 - NettyEventExecutorGroup Camel (camel-1) thread #3 - NettyEventExecutorGroup INFO [route1] - >> Thread name : Camel (camel-1) thread #3 - NettyEventExecutorGroup Camel (camel-1) thread #2 - NettyEventExecutorGroup INFO [route1] - >> Thread name : Camel (camel-1) thread #2 - NettyEventExecutorGroup Camel (camel-1) thread #1 - NettyEventExecutorGroup INFO [route1] - >> Thread name : Camel (camel-1) thread #1 - NettyEventExecutorGroup Camel (camel-1) thread #0 - NettyEventExecutorGroup INFO [route1] - >> Thread name : Camel (camel-1) thread #0 - NettyEventExecutorGroup Camel (camel-1) thread #4 - NettyEventExecutorGroup INFO [route1] - >> Thread name : Camel (camel-1) thread #4 - NettyEventExecutorGroup Camel (camel-1) thread #3 - NettyEventExecutorGroup INFO [route1] - >> Thread name : Camel (camel-1) thread #3 - NettyEventExecutorGroup Camel (camel-1) thread #4 - NettyEventExecutorGroup INFO [route1] - >> Thread name : Camel (camel-1) thread #4 - NettyEventExecutorGroup Camel (camel-1) thread #0 - NettyEventExecutorGroup INFO [route1] - >> Thread name : Camel (camel-1) thread #0 - NettyEventExecutorGroup Camel (camel-1) thread #2 - NettyEventExecutorGroup INFO [route1] - >> Thread name : Camel (camel-1) thread #2 - NettyEventExecutorGroup Do I have to use another param to set the ThreadPool used by Netty4-http ?
