Exception: org.apache.http.impl.execchain.RetryExec execute INFO: I/O exception (org.apache.http.NoHttpResponseException) caught when processing request to {}->http://0.0.0.0:64451: The target server failed to respond

Above said exception is been thrown after few cases executed. However there are no parallel cases been executed.

I figured out problem, issue was somehow app is going to background and a icon used to come on foreground. So appium time out was happening after 10min(which was set). But I don't understand why retry(RetryExec execute) is happening every 10min.

Moving to java client

[geetha5]

Can someone please respond if anybody has thoughts/Ideas on how to fix it?

[SrinivasanTarget]

@geetha5 @GaneshvrBhat Can you share sample code and sample app to reproduce this error as I could not reproduce it locally.

We are also seeing same logs (httpclient-4.5.12). Anyone found any solution for this.

int timeOut = 60000 int defaultMaxPerRoute = 50; RestTemplate restTemplate = new RestTemplate(getRequestFactory(timeOut, defaultMaxPerRoute));

private HttpComponentsClientHttpRequestFactory getRequestFactory(int timeout, int defaultMaxPerRoute) { HttpComponentsClientHttpRequestFactory clientHttpRequestFactory = new HttpComponentsClientHttpRequestFactory(); if (timeout > 0) { clientHttpRequestFactory.setConnectTimeout(timeout); clientHttpRequestFactory.setReadTimeout(timeout); } CloseableHttpClient client = HttpClientBuilder.create() .setConnectionManager(poolingConnectionManager(defaultMaxPerRoute)).build(); clientHttpRequestFactory.setHttpClient(client); return clientHttpRequestFactory; }

private PoolingHttpClientConnectionManager poolingConnectionManager(int defaultMaxPerRoute) {
	PoolingHttpClientConnectionManager poolingConnectionManager = new PoolingHttpClientConnectionManager();
	poolingConnectionManager.setDefaultMaxPerRoute(defaultMaxPerRoute);
	return poolingConnectionManager;
}
