Amazon join exception exception sqs reset

Question

I use AmazonSQSAsyncClient to connect to Amazon SQS, but sometimes I see the following execution in the logs:

INFO [AmazonHttpClient:444] Unable to execute HTTP request: Connection reset java.net.SocketException: Connection reset at java.net.SocketInputStream.read(SocketInputStream.java:168) at com.sun.net.ssl.internal.ssl.InputRecord.readFully(InputRecord.java:293) at com.sun.net.ssl.internal.ssl.InputRecord.read(InputRecord.java:331) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:798) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readDataRecord(SSLSocketImpl.java:755) at com.sun.net.ssl.internal.ssl.AppInputStream.read(AppInputStream.java:75) at org.apache.http.impl.io.AbstractSessionInputBuffer.fillBuffer(AbstractSessionInputBuffer.java:166) at org.apache.http.impl.io.SocketInputBuffer.fillBuffer(SocketInputBuffer.java:90) at org.apache.http.impl.io.AbstractSessionInputBuffer.readLine(AbstractSessionInputBuffer.java:281) at org.apache.http.impl.conn.DefaultHttpResponseParser.parseHead(DefaultHttpResponseParser.java:92) at org.apache.http.impl.conn.DefaultHttpResponseParser.parseHead(DefaultHttpResponseParser.java:62) at org.apache.http.impl.io.AbstractMessageParser.parse(AbstractMessageParser.java:254) at org.apache.http.impl.AbstractHttpClientConnection.receiveResponseHeader(AbstractHttpClientConnection.java:289) at org.apache.http.impl.conn.DefaultClientConnection.receiveResponseHeader(DefaultClientConnection.java:252) at org.apache.http.impl.conn.ManagedClientConnectionImpl.receiveResponseHeader(ManagedClientConnectionImpl.java:191) at org.apache.http.protocol.HttpRequestExecutor.doReceiveResponse(HttpRequestExecutor.java:300) at com.amazonaws.http.protocol.SdkHttpRequestExecutor.doReceiveResponse(SdkHttpRequestExecutor.java:66) at org.apache.http.protocol.HttpRequestExecutor.execute(HttpRequestExecutor.java:127) at org.apache.http.impl.client.DefaultRequestDirector.tryExecute(DefaultRequestDirector.java:712) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:517) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:906) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:805) at com.amazonaws.http.AmazonHttpClient.executeHelper(AmazonHttpClient.java:380) at com.amazonaws.http.AmazonHttpClient.execute(AmazonHttpClient.java:229) at com.amazonaws.services.sqs.AmazonSQSClient.invoke(AmazonSQSClient.java:2169) at com.amazonaws.services.sqs.AmazonSQSClient.getQueueUrl(AmazonSQSClient.java:468) at com.amazonaws.services.sqs.AmazonSQSClient.getQueueUrl(AmazonSQSClient.java:1476) 

I am using AmazonSQSAsyncClient through the application as singleton.

The following is a snippet of code.

 static{ if(sqsObj == null){ sqsObj = new AmazonSQSAsyncClient(new ClasspathPropertiesFileCredentialsProvider("app.properties")); sqsObj.setRegion(Region.getRegion(Regions.valueOf("sample region")); } } 

Using sqsobj, I perform operations such as queuing, sending messages, and receiving messages. It works fine, but throws an exception for a while, as mentioned above. After restarting the application, it has been working fine for some time.

I am using aws-java-sdk-1.7.1. Please suggest about it.

"connection reset" means that the other side (ie server) has closed the connection.

Internally, the SDK creates and reuses the http connection so that it does not open the connection every time you make a request.

A log message tells you that the connection was reset, but usually there is nothing to worry about. The SDK will automatically try again in such cases. Therefore, if you only observe this in the magazines, but everything works as expected, you probably should not worry about it.
