SocketException : Broken Pipe (Write Failed) while using FlatFileItemReader in Spring Batch

Question

I am using Spring - Batch FlatFileItemReader to read my input stream.

@Bean
@StepScope
public FlatFileItemReader<Employee> flatFileItemReader(){

  InputStream inputStream = apiCallGetInputStream();
  return new FlatFileItemReaderBuilder<Employee>().
             .name("reader")
             .resource(new InputStreamResource(inputStream))
             .encoding("UTF-8")
             .delimited()
             .delimited("|")
             .names("id","name","dept")
             .linesToSkip(2)
             .targetType(Employee.class)
             .build();
}

public InputStream apiCallGetInputStream(){
   InputStream inputStream = null;
   try{
      Url url=new URL("myUrl");
      final HttpsURLConnection connection = (HttpsURLConnection)url.openConnection();
      setConnectionParams();
      inputStream = connection.getInputStream();
   }catch(IOException ex){
      log.error(ex);
   }
   return inputStream;
}

public void setConnectionParams(HttpsURLConnection connection){
    connection.setRequestProperty("Content-type","application-json");
    connection.setRequestMethod("GET");
    connection.setReadTimeout(600000);
    connection.setConnectTimeout(600000);
}

Please note : response I am getting is TXT format delimited with | character

ex:

201|maxwell|eng

After reading 80K records everytime suddenly I am getting
