      Our build server contains lots of modules, and is frequently under high load (we're adding slaves to distribute the load over different servers).
      The problem is that sometimes, under high load the builds fail when trying to parse the cobertura files.
      These are the details of the error:

      Any help would be appreciated.
      Let me know if you need more information, I'll be glad to give it !

      Thanks a lot,

          [JENKINS-11251] Cannot parse coverage results Premature end of file.

          To determine the version I've used:
          jar xvf slave.jar jenkins/remoting/jenkins-version.properties
          According to this file we have version=2.4

          Frederic Marius added a comment - To determine the version I've used: jar xvf slave.jar jenkins/remoting/jenkins-version.properties According to this file we have version=2.4

          We have the same issue, not using slaves. It's happening on our master Jenkins instance, randomly.

          We're running Jenkins 1.433 and using cobertura maven plugin 2.3.

          I can upgrade Jenkins see if that changes anything.

          Looking at the cobertura plugin, I see that it's not reading from a pipe (which I assumed so incorrectly earlier.) Instead, this is loading a local file. That changes everything.

          Bumped up the priority of this plugin to make it a candidate for LTS backporting.

          When communicating with remoting < 2.15, this allows them to continue to
          perform some degree of syncing, so that they can still enjoy the fix for
          JENKINS-9189.

          None of these code is exposed via API outside remoting, so at some point
          we can revert this change to simplify the code a bit and eliminate the
          redundancy, because as long as >= 2.15 remoting talk to each other,
          PipeWriter does everything we need.
