Question

我们在同一个tomcat服务器上部署了三个应用程序A，B和C.在A到B之间发生HTTP调用（REST CALL）和从B到C的另一个http调用（REST CALL）

我们最初使用同步HTTP调用，最近我们将代码更改为异步调用。我们使用了HttpAsyncClients（应用程序A来调用应用程序B）并且（申请B称为申请C）..

我们得到间歇性的org.apache.http.ConnectionClosedException：有时我们在应用程序A的日志（Async Client到B）和应用程序B中的某个时间（Async Client到C）中获得此异常

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

并且对于每个请求，我们都给出了

的超时

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

请在下面找到堆栈跟踪：

请注意这个问题不重复 Intermittent ConnectionClosedException with httpasynclient stacj跟踪是完全不同的。事件中这个问题是间歇性的。

Apache ConnectionClosedException：连接已关闭，HttpAsyncRequestExecutor.endOfInput（HttpAsyncRequestExecutor.java:344）
