Description

I'm running out of sockets after a few minutes. The same client works fine on Mac OS X (JMX 1.5.0_07).
The client sends 2 requests type to the server(s):

• type 1: 0.2 requests/second. Service time 50 seconds (avg)
• type 2: 1.8 requets/seconds. Service time 5 seconds (avg).

After about 10 minutes the client crashes because the client machine runs out of sockets (ulimit -n = 1024):

All ServiceClient objects share the following ConfigurationContext:

ConfigurationContext configurationContext = ConfigurationContextFactory.createConfigurationContextFromFileSystem(null, null);
HttpClient httpClient = new HttpClient(new MultiThreadedHttpConnectionManager());
configurationContext.setProperty(HTTPConstants.REUSE_HTTP_CLIENT, Boolean.TRUE);
configurationContext.setProperty(HTTPConstants.CACHED_HTTP_CLIENT, httpClient);
