Jenkins web GUI hangs when using a computer with more then 70 CPU's

XMLWordPrintable

      From version 2.117 jenkins web GUI hangs when using more then 70 cpus,  between 64 and 70 jenkins GUI is not updated correctly. Using wget instead of browser only to show what's failing, but using Chrome in real life

      Works fine (version 2.135 with 64 cpus)

      $docker run --cpuset-cpus=0-64 -p 8080:8080 -p 50000:50000 jenkins/jenkins:latest
      Running from: /usr/share/jenkins/jenkins.war
      webroot: EnvVars.masterEnvVars.get("JENKINS_HOME")

      ....
