          [JENKINS-42533] Trying to unexport an object that's already unexported

          Oleg Nenashev added a comment -

          Please provide...

          • Jenkins System log for the timeframe of the issue
          • Remoting (slave.jar) version on the remote side
          • Jenkins agent log for the timeframe of the issue

          Likely it's just another occurrence of JENKINS-23271

          Don't know which slave caused the problem or where to get old agent log. We are using ssh to launch agent and the jenkins is restarted already because it stuck for some reason. Problem for jenkins started after 2.48. Now we are using 2.49 version.

          So it is related to the fix of JENKINS-22853 in https://github.com/jenkinsci/remoting/pull/97/files

          There I have fixed the ProxyOutputStream#EOF command, but not ProxyOutputStream#Unexport(). Maybe makes sense to fix it as well, will investigate

          Unfortunately I have no capacity to work on Remoting in medium term, so I will unassign it and let others to take it. If somebody is interested to submit a pull request, I will be happy to help to get it reviewed and released.
