We are still validating Apache Camel 2.11.0, but would you please check below scenario cause issue or not? When connection remove from the pool. Are you plane to use PoolingClientConnectionManager in Apache Camel 2.10.4?
scenario ====== I am more worry about maxTotalConnections connection. If i have 100 routes and each create 2 connections. we reach the maxTotalConnections. Since we are not setting connTTL( connection lifetime, <=0 implies "infinity"), so connection is not remove from connection pool and 101 route will throw Connection refused error. -- View this message in context: http://camel.465427.n5.nabble.com/Camel-http4-component-throws-Connection-refused-error-tp5726673p5727565.html Sent from the Camel Development mailing list archive at Nabble.com.
