      Description

      We are using Solr 4.0 and run intensive performance/data-integrity/endurance tests on it. In very rare occasions the content of two concurrent requests to Solr get mixed up. We have spent a lot of time narrowing down this issue and found that it is a bug in Jetty 8.1.2. Therefore of course we have filed it as a bug with Jetty.
      Official bugzilla: https://bugs.eclipse.org/bugs/show_bug.cgi?id=392936
      Mailing list thread: http://dev.eclipse.org/mhonarc/lists/jetty-dev/threads.html#01530

      The reports to Jetty is very detailed so you can go and read about it there. We have found that the problem seems to be solved in Jetty 8.1.7. Therefore we are now running Solr 4.0 (plus our additional changes) on top of Jetty 8.1.7 instead of 8.1.2. You probably want to do the same upgrade on the Apache side sometime soon.

      Alt least now you know what to tell people if the start complaining about mixed up requests in Solr 4.0 - upgrade the Jetty underneath to 8.1.7 (or run tomcat or something)

          Here is the patch we did. But is sounds like you already did it. Our patch fits on top of Solr 4.0.0 (actually revision 1394844 from lucene_solr_4_0 branch)

          Thanks for tracking that down Per!
          Sounds like we should definitely upgrade to the latest Jetty 8. I've marked this for 4.1
