  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
