Major Description
We are trying to load test shindig with our GWT gadgets. Both shindig server and gadgets running on the same server. We isolated the ajax call and ran it in multiple simultaneous user scenarios. We increased the DEFAULT_CONNECT_TIMEOUT_MS and DEFAULT_READ_TIMEOUT_MS values in BasicHttpFetcher source code to eliminate the timeout errors. As we increase the load from 1 to 5, 10, 25 users, we start geting this error. I'm wondering if BasicHttpFetcher is handling connection pool correctly. Any insight would be highly appreciated. Thanks.
