      Description

      We are getting a java.lang.OutOfMemoryError exception when getting the remote log.

      Some notes:

      • The path/ and path\ comes from the "Remote Name"/"Local Name" settings solution from Issue JENKINS-13264
      • We are using Jenkins 1.464 with the 2.4-SNAPSHOT version of the CVS plugin, but may not have been caused by this specific version
      • The arguments setting in the jenkins.xml file currently has -Xms1024m (anything larger and Jenkins service won't start)
      • The CVS module has many legacy projects spread out, and thus, contains more than 7,000 directories and many more files
      • Things had worked with the 1.6 plug-in & CVSNT client, but it also occasionally timed out getting the changelog, hence our testing of the 2.x plug-ins
