I can second that. Cheers Oliver

Jmeter log was also showing 'Connection Timed Out'. Following is the exception, > java.net.ConnectException: Connection timed out: connect > at java.net.PlainSocketImpl.socketConnect(Native Method) at > java.net.PlainSocketImpl.doConnect(Unknown Source) at > java.net.PlainSocketImpl.connectToAddress(Unknown Source) at > java.net.PlainSocketImpl.connect(Unknown Source) at > java.net.Socket.connect(Unknown Source) at > java.net.Socket.connect(Unknown Source) at > sun.net.NetworkClient.doConnect(Unknown Source) at > sun.net.www.http.HttpClient.openServer(Unknown Source) at > sun.net.www.http.HttpClient.openServer(Unknown Source) at > sun.net.www.http.HttpClient.(Unknown Source) at > sun.net.www.http.HttpClient.New(Unknown Source) at > sun.net.www.http.HttpClient.New(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(Unknown Source)... > Since today I was facing the ' java.io.IOException: Stream closed' exception even with 5 threads, I reduced the test case to 3 threads. I observed the following results. On Running two test cases of 3 threads each , using separate Jmeter instances,simultaneously from a single machine using 70Kbps connection - Some requests are failing with exception ' java.io.IOException: Stream closed'. On Running two test cases of 3 threads each ,simultaneously from different machines using 70Kbps connections - All requests are passing. Also, even if the requests are failing in Jmeter, I did'nt observe any Error in WebServer logs. Hope the findings will be of some help, Regards, Richa sebb <[EMAIL PROTECTED]> wrote: As I understand it: * this is happening with both HTTP Samplers. These use different implementations. * neither is reporting timeout errors, which I believe they would do - if they occurred. It does not look like timeouts to me, nor does it look like a problem in JMeter. But I could be wrong, as I don't have first-hand experience of the problem. S.
