Hi All,

Would anyone know how to configure the timeout values for the below connection 
pool or the connection pool itself? Been having some issues lately in a test 
environment with this and the timeout check seems to happen every few 
milliseconds producing huge amounts of log files.
We're suspecting it's a network issue that's causing this as there is nothing 
much between the REST endpoint on the buffer queue and only if there is some 
decent load on the endpoint (10req/sec or so):

rest(restEndpoint).post(postEndpoint)
     .type(FeedbackRequest.class)
     .route()
.process(this::process)
     .startupOrder(Integer.MAX_VALUE - 2)
.marshal().json(JsonLibrary.Jackson, String.class)
.to(feedbackEndpoint)
     .endRest();

where process() just sets a persistence header for RabbitMQ to flush the 
message to disk:


exchange.getIn().setHeader("rabbitmq.DELIVERY_MODE", 2);
