We used to have the same exceptions in our logs as well. We just turned off GZIPCompression at Jenkins level and everything went fine afterward… This is done by adding the following arguments to the Jenkins launch command:
-Dorg.kohsuke.stapler.compression.CompressionFilter.disabled=true On the other hand, we also notice many more exceptions about Jenkins being unable to parse some of its data – something like "unable to parse date: 0" Builds artefacts are kept in their own directory, named after the build number. In addition (on Unix at least), a symlink is created with the build date pointing to the directory where the actual build files are stored. In our case, we noticed that old builds didn't have any symlinks pointing to them – so they couldn't be accessed "by date". Hence the exceptions in the log about being unable to parse the build number into a date… We simply deleted those (very) old builds, the exceptions disappeared and Jenkins became faster. Hope this helps… /Bertrand From: David Resnick <abune...@gmail.com<mailto:abune...@gmail.com>> Reply-To: "jenkinsci-users@googlegroups.com<mailto:jenkinsci-users@googlegroups.com>" <jenkinsci-users@googlegroups.com<mailto:jenkinsci-users@googlegroups.com>> Date: Wednesday 24 October 2012 07:21 To: "jenkinsci-users@googlegroups.com<mailto:jenkinsci-users@googlegroups.com>" <jenkinsci-users@googlegroups.com<mailto:jenkinsci-users@googlegroups.com>> Subject: Re: Very long load time for main dashboard since 1.486 Thanks!

I am not able though to correlate the exceptions with the long loading times. Right now my main dashboard loads very quickly (with a Jenkins instance that has been up for over 5 days). - David On Tuesday, October 23, 2012 10:40:58 AM UTC+2, jcsirot wrote: Helle David, I'm facing the same issue too. Looking at the log I noticed this exception. I don't know if it is linked but after this exception has been printed in the log trail the dashboard loads immediately. Did someone have any unexpected exception in the log file?

Longest load times are for the main dashboard (which includes over 100 jobs and thousands of builds) -- I just timed 4 minutes 45 seconds for the page to load. Note that all pages do load eventually. Has anyone else encountered this regression? - David
