Created attachment 238436 [details] views are missing by fresh browser Hello, we have installed 3.1.0-RC for an existing hudson farm. We are experiencing the following problem: If you start a fresh browser and visit the start page/overview of hudson (i.e. http://hudson.mycompany.com/hudson/) the right part with the views is missing (see attachement). Additionally, an InvocationTargetException appears in the log (see attachement). You can workaround the problem by following these step: If you visit a link for a slave or a project the problem disappears within the sesssion. The overview shows the views at the right hand. seems the slave/project pages sets an JSESSIONID-Cookie which solves the problem. This matches the message of the stacktrace "Cannot create a session after the response has been committed". The problem occurs every time a fresh browser has been started.
Created attachment 238437 [details] InvocationTargetException occuring in the log Ahem, we installed 3.1.1-RC, not 3.1.0-RC ;-)
I don't reproduce this problem in Firefox, Chrome or Safari. What browser are you using?
We see the phenomenon on Firefox, on Chrome, and on Internet Explorer.

Marc, can you give some more details - How do you run Hudson, as a standalone server or deploy to an appserver I'm not sure if this is specific to 3.1.1 Generally this error occurs if the HTTP response buffer is not large to hold response created (too many jobs and columns in the table) and overflows, then a forced flush happens (commit http://docs.oracle.com/javaee/5/api/javax/servlet/ServletResponse.html#flushBuffer%28%29). However, if the user session is not yet created, then the server throws this error. I'm not sure which appserver you are using, but in tomcat you can set the buffer size in the HTTP connector in the server.xml
Looking at the exception, this is specifically caused by audit_trail plugin. To test, can you disable that plugin and see if you still see the error.
Hi Winston, we have tried to deactivate audit_trail plugin, without any effect. Additionally, we have put the following settings in server.xml according to your guidance and this article http://stackoverflow.com/questions/7271186/how-do-i-set-tomcat-response-buffer-size-trough-configuration bufferSize="64000" maxHttpHeaderSize="64000" socket.appWriteBufSize="64000" socket.appReadBufSize="64000" But these settings didn't help either. :-( Our system is as follows * Hudson 3.1.1-RC (previously 2.2.1 was installed) as WAR * deployed on Tomcat 6.0.18 * audit_trail plugin has version 1.8-h-1 * Operating System fpr the master is Linux 2.6.18-371.1.2.el5 #1 SMP x86_64 x86_64 x86_64 GNU/Linux * JDK 1.6.0_18 * round about 500 hudson jobs * nearly 50 slaves * overview has 26 tabs and defaults to a tab showing the failed jobs (16 at the moment) Furthermore, we have tried to remove the cookie JSESSIONID in the browser after following the workaround. The problem reappears immediatly in the same browser session.

(In reply to Marc Pompl from comment #8) Hi Marc, we are looking at the issue and trying to reproduce it on our side. One of the reason why we introduced Team Concept http://wiki.eclipse.org/Hudson-ci/features/Team_Concept in Hudson 3.1.0 is to isolated Jobs per team. The jobs are isolated based on teams so that only jobs belong to the logged in users team is displayed. This solves the problem of too many jobs being displayed all the time and having to create too many tabs.
(In reply to Winston Prakash from comment #9) Just to double check I upgraded hudson-on-hudson (http://ci.hudson-ci.org/) to Hudson 3.1.1 and not seeing the issue. It runs on a Linux VM Linux 2.6.32-400.1.1.el5uek #1 SMP Mon Jun 25 20:25:08 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux Main differences I see are - Deployed on tomcat apache-tomcat-7.0.34 - java version "1.7.0_11" Java(TM) SE Runtime Environment (build 1.7.0_11-b21) - Number of jobs are less (about 100)
(In reply to Winston Prakash from comment #10) Out of curiosity, can you try Hudson 3.0.1 instead of Hudson 3.1.1
(In reply to Winston Prakash from comment #11) > (In reply to Winston Prakash from comment #10) > > Out of curiosity, can you try Hudson 3.0.1 instead of Hudson 3.1.1 Sorry Winston, currently we only have a live system (unfortunately, no test) and I definitely want to avoid problems when downgrading to version 3.0.1 - so close to the Christmas holidays ;-) A perhaps more important aspect is that we use the Servlet Container Security Realm with matrix-based security. best regards, Thomas

I admire your courage or should I say faith in Hudson :) Why I said to try with 3.0.1 was, in Hudson 3.1.0 we introduce a new data model to reduce memory footprint. I spoke to the engineer who implemented the new data model yesterday and clarified that in memory objects will be allowed to garbage collected only if the user is inactive for more than 1 minute and never with in the scope of the HTTP request. This data model change introduces slight delay in page load, but with enormous advantage in overall memory foot print reduction. When I leave the browser inactive for more than 1 minute, I do see a slight delay in page load. Initially the page looks like your screenshot, but recovers with in few seconds. I just wanted to make sure, the new data model is not the one causing phenomenon you see (though I doubt that). Have a great Christmas Holidays and looking forward to work with you guys in the new year.
(In reply to Winston Prakash from comment #13) Can you send us the list of plugins you have installed. We will make sure those plugins are installed in our test environment.
