chowdareddy somu updated HTTPCORE-238:
--------------------------------------
Description:
Hi,
We are using the HttpClient4.0.3(latest) version for our application where we
need to serve the http request to our web app by calling the underlying
services.
Application gets an average 50 threads at a time and we are maintaining the
connection pool on per host basis. we configured the following HttpParam
values.. And we are calling the abort() and consumeContent() methods if there
are any exceptions due to backed service problem, and for success requests we
are extracting the response using the get content method( InputStream is =
httpResponse.getEntity().getContent())
Application runs contionusly for 3 to 4 hrs fine, after that its getting the
out of connections and it throws below exception..
Config Values
http.connection.timeout = 5000
http.socket.timeout = 300000
http.conn-manager.timeout = 1000
http.conn-manager.max-per-route = 100
http.conn-manager.max-total = 100
private static HttpConnectionManagerFactory instance = null;
private Map<String, ClientConnectionManager> map = new HashMap<String,
ClientConnectionManager>();
private HttpConnectionManagerFactory() {
}
public static synchronized HttpConnectionManagerFactory getInstance() {
if (instance == null) {
instance = new HttpConnectionManagerFactory();
}
return instance;
}
public synchronized ClientConnectionManager getConnectionManager(URI
uri) {
if (!map.containsKey(uri.getHost())) {
HttpParams params =
HttpProperties.getInstance().getHttpParams(uri);
SchemeRegistry registry = new SchemeRegistry();
Scheme http = new Scheme("http",
PlainSocketFactory.getSocketFactory(), 80);
registry.register(http);
map.put(uri.getHost(), new
ThreadSafeClientConnManager(params, registry));
}
return map.get(uri.getHost());
}
public HttpClient getClient(HttpUriRequest request) {
ClientConnectionManager connectionManager =
HttpConnectionManagerFactory.getInstance().getConnectionManager(request.getURI());
HttpParams params =
HttpProperties.getInstance().getHttpParams(request.getURI());

HttpClient httpClient = HttpClientFactory.getInstance().getClient(httpRequest);
tracker.startTimer();
HttpResponse httpResponse = null;
try {
try {
httpResponse =
httpClient.execute(httpRequest);
} finally {
tracker.stopTimer();
}
StatusLine statusLine =
httpResponse.getStatusLine();
tracker.setStatusLine(statusLine);
