Yes, the stack trace shows that the error is occurring in the Java code, and it is not a JMeter problem per se. But what causes the connection to time out? Is it necessarily a problem with the server? Presumably a proxy could cause the error. If the JMeter host runs out of sockets, can that cause the error? - I would expect that to cause a different error. It might be worth trying the HttpClient version of the HTTP sampler, though I doubt it will make much difference, as it will still use the same Java sockets. But if it does change the behaviour significantly, then it might give some clues as to what is happening. > Thanks, > > Seth > > ---------------------------------------------- > > 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.protocol.https.HttpsClient.<init>(Unknown Source) > at sun.net.www.protocol.https.HttpsClient.New(Unknown Source) > at > sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.getNewHttpClient(Unknown > Source) > at sun.net.www.protocol.http.HttpURLConnection.plainConnect(Unknown > Source) > at > sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(Unknown > Source) > at sun.net.www.protocol.https.HttpsURLConnectionImpl.connect(Unknown > Source) > at > org.apache.jmeter.protocol.http.sampler.HTTPSampler.sample(HTTPSampler.java:457) > at > org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.downloadPageResources(HTTPSamplerBase.java:1044) > at > org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.resultProcessing(HTTPSamplerBase.java:1253) > at > org.apache.jmeter.protocol.http.sampler.HTTPSampler.sample(HTTPSampler.java:537) > at > org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:889) > at > org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:875) > at org.apache.jmeter.threads.JMeterThread.run(JMeterThread.java:298) > at java.lang.Thread.run(Unknown Source) > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
