I agree with you. one practice I found is to log only the message of these errors (some are expected) but log the full trace if debug is enabled

@ppatierno

did you look at https://vertx.io/docs/vertx-core/kotlin/#_data_objects_builders ?

I think we could have this static util method in vertx-web-client if you can make a PR.

if that is executed from the event loop then the semaphore will self deadlock the application

is the code executed from the event loop ?

are you using Vert.x 4 ? if yes instead you should do something like ``` for (data in dataChannel) { writeStream.write(data).await() } ``` otherwise I think the best would be...

would a TCP idle timeout work in this case ?

I think that's a more general question about dead connection detection : does MQTT have PING message ?

@ctron there is not such timeout because it's protocol dependant (like PING frames for websocket, HTTP/2, etc...)
