Hi,

I have got a Vertx Exception: java.io.IOException: Connection reset by peer

It only happens when I run the program at AWS, not always, but often when send new requests. It does not happen when I run the program at my local.

The program has two layers of asynchronous function. First, asynchronous call each content provider. Second, asynchronous call each url inside the content provider. I can receive content from the provider, however, the connection reset by peer happens after it. Please help me figure out how to fix it. Thanks.

Vert.x version is 3.4.2

Hi,

this is a normal and expected behavior.

It means the client did not do a clean termination of the TCP connection, this is reported by the JVM as an exception.

HI Julien,

Thanks for your reply. But you mean "client" is my server side, which need to clean termination of the TCP connection, or it is content provider issue?

I just curious why it is working at my localhost, but it fails at AWS.

Is there any more info I can refer to?

Thanks!

callTrendingAndConvert() is asynchronously called by 5 futures.

The problem I am confused is why it is running well at my local but not at AWS.

On AWS, the connection reset always happens for a new request or a couple of new requests. It still happens when send requests repeatedly, but rare. Sometimes, one or two connection out of FIVE connections are reset, not all of them are reset. Hope this info helps. If you need more info, please let me know. Thanks.

And I have checked the previous response you had given on similar issues, which were really helpful.

Thanks.
