Apache ConnectionClosedException: Connection closed,HttpAsyncRequestExecutor.endOfInput(HttpAsyncRequestExecutor.java:344)

we have three applications A,B and C deployed on same tomcat server.There is an HTTP call that happens between A to B(REST CALL) and Another http call from B to C(REST CALL)

We were using synchronous HTTP call initially,recently we changed our code to Asynchronous call. We have used HttpAsyncClients for (Application A to call Application B) and for (Application B to call Application C)..

we are getting intermittent org.apache.http.ConnectionClosedException: Some time we are getting this exception in Logs of application A(Async Client to B) and some time in Application B(Async Client to C)

 CloseableHttpAsyncClient  client = HttpAsyncClients.custom()
                    .setMaxConnPerRoute(100))
                    .setMaxConnTotal(config.getInt(150)).build();

and for Every request we gave timeout of

final RequestConfig params = RequestConfig.custom().setConnectTimeout(300000) // 5min
                    .setSocketTimeout(300000).setConnectionRequestTimeout(300000).build();

Please Note this question is not duplicate of Intermittent ConnectionClosedException with httpasynclient stacj trace is completely different..And event this issue happens intermittent.
