问题 With OkHttp library, application is facing following SocketTimeoutException issue. If request size is less, then it is working fine(Less than 1MB). I am getting this exception within 10 seconds, even my socket timeout( readTimeout ) value is much higher. It is consistently failing for a request(Size is 1.8MB). When I executed a request with HttpUrlConnection it is working fine. What could be a possible reason of failure? 03-29 12:16:38.997 32066-4018/com.mobile W/System.err: java.net

I have a thread running under tomcat which creates a HttpUrlConnection and reads it through BufferedInputStream. After fetching data for some urls, it stalls.

I take a look at HttpUrlConnection API description but I couldn't answer my question. Updated: Please see my test: public static void main(String[] args) {
