  • We are restarting hudson each Sunday afternoon to evade problems with memory leaks and have a couple of nightly builds that kick in at midnight. The scenario is that Hudson is fresh when multiple builds kick in, that is its remote class loader did not have a chance to read any classes yet. We have 3 executors defined. I suppose that the SCM poll action that is sent in many build procedures causes multiple requests to load classes for the SCM (we use slightly hacked version of CVS SCM). We are getting the following exception: java.lang.LinkageError: loader (instance of hudson/remoting/RemoteClassLoader): attempted duplicate class definition for name: "hudson/model/ModelObject" I have looked around on the web and found this (http://jira.codehaus.org/browse/JETTY-418) that lead me to believe that lack of synchronization while loading classes in remote class loader is the cause.
