title: How to find Jenkins build jobs consuming high CPU and Memory
body: <p>So far, Our Jenkins service hanging everyday, we cannot access the web page, I have to restart Jenkins services after hanging.</p>
  
  <p>In Jenkins, I only set 4 of executors. Sometime, when 4 build job are running, the CPU load almost 90%, I guess that is a reason why Jenkins dies.</p>
  
  <p>So how can I find which build job consume high CPU, and how can I find a root cause why the Jenkins die, I check in system log, but did not find any useful info.
  I'm running Jenkins version 2.150.1 in Ubuntu 16.04.
  Thanks.</p>
