Regarding the CloudSuite Web Serving benchmark, has anyone experienced the web server returning 504 error responses, or have any idea why this may be happening and how to fix it?
I have modified the Faban driver to run longer, and so far all of 3 long tests (30 minutes or longer) have eventually degraded to the point where all responses are 504 messages. Here is an example from Faban's driver.log file: Sep 01, 2016 2:02:29 AM com.sun.faban.driver.engine.AgentThread logError WARNING: ElggDriverAgent[0].59.sendChatMessage: Server returned HTTP response code: 504 for URL: http://192.168.1.2:8080/action/elggchat/post_message?__elgg_token=57e9c8b81e4cdffb712221df75561baf&__elgg_ts=1472694493 java.io.IOException: Server returned HTTP response code: 504 for URL: http://192.168.1.2:8080/action/elggchat/post_message?__elgg_token=57e9c8b81e4cdffb712221df75561baf&__elgg_ts=1472694493 at sun.reflect.GeneratedConstructorAccessor7.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:526) at sun.net.www.protocol.http.HttpURLConnection$6.run(HttpURLConnection.java:1677) at sun.net.www.protocol.http.HttpURLConnection$6.run(HttpURLConnection.java:1675) at java.security.AccessController.doPrivileged(Native Method) at sun.net.www.protocol.http.HttpURLConnection.getChainedException(HttpURLConnection.java:1673) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1246) at com.sun.faban.driver.transport.sunhttp.SunHttpTransport.fetchResponse(SunHttpTransport.java:673) at com.sun.faban.driver.transport.sunhttp.SunHttpTransport.fetchURL(SunHttpTransport.java:557) at com.sun.faban.driver.transport.sunhttp.SunHttpTransport.fetchURL(SunHttpTransport.java:519) at workload.driver.Web20Driver.sendChatMessage(Web20Driver.java:638) at sun.reflect.GeneratedMethodAccessor6.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.sun.faban.driver.engine.TimeThreadWithBackground.doRun(TimeThreadWithBackground.java:197) at com.sun.faban.driver.engine.AgentThread.run(AgentThread.java:202) Caused by: java.io.IOException: Server returned HTTP response code: 504 for URL: http://192.168.1.2:8080/action/elggchat/post_message?__elgg_token=57e9c8b81e4cdffb712221df75561baf&__elgg_ts=1472694493 at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1628) at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:468) at com.sun.faban.driver.transport.sunhttp.SunHttpTransport.fetchResponse(SunHttpTransport.java:654) ... 8 more
