java.net.SocketException- Connection reset by peer : socket write error

[Rinki Bhandari]

Hi,

We are facing issue regarding java.net.SocketException every time On starting Esper.

Environment used : 

- RabbitMQ server - 3.8.14

- Esper version: 8.7.0

- Erlang - Erlang 23.1

- Java - jdk1.8.0_271

- RabbitMQ Java Client 5.11.0

Also we are using DefaultConsumer to consume mesages from the channel. Here are the lines used -

DefaultConsumer consumer = new DefaultConsumer (channel)

{

 @Override 

 public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException

String message = new String(body,"UTF-8");

String rountingKey = envelope.getRoutingKey();

callBack.amqpDataReceived(message,routingKey);

}

channel.basicConsume(queue,true,consumer);

callBack.amqpReceiverStared();

Below is the screenshot attached of error. Earliest help would be appreciated.

[Arnaud Cogoluegnes]

The server logs would help to find out about the reason of the connection closing.

Hi  Arnaud,

Thank you for replying. I would like to know which server log would be required?  Is it RabbitMQ or our application server log?

Regards

Hi,

Below is the attached log file for RabbitMQ node.

[Arnaud Cogoluegnes]

The connection seems to be closed by the client according to the logs. The error occurs on a basicPublish called from some application heartbeat utility. Are you sure the connection is not closed in another place of the application and this utility keeps on working against this closed connection?

Yes I am  sure the connection is not closed in another place of the application. Also I am using RabbitMQ client v5.0.0 at .NET end and RabbitMQ client v5.11.0 at Java end. It showed me QueueingConsumer/QueueingBasicConsumer as  deprecated  so I made below changes in code. 

[M K]

There isn't much that can be said from this log or code snippets. None of them explain why a socket write could time out

but according to the log, your applications open N connections and never close any. It *may* be an indication of a connection leak

(which is not related to socket write failures but a very serious issue if true) [1].

A traffic capture [2] would provide a lot more relevant information about what both sides of this connection do.

Hi,

We have opened limited connections and disposed them correctly. There is no issue of connection leak. (verified). We need an example

which is perfect way to implement channels and consumers with EventingBasicConsumer's Received event at .Net side and  DefaultConsumer at java end

Thanks
