    Description

      Hello,

      I regularly meet the above problem : Jenkins use nearly 100% of the four CPU, web api is not accessible, and a "Oops!" webpage appears after tens minutes or some hours of "work".

      Attached :

      • jenkins' log
      • screenshot of htop command that show Jenkins process that use CPU
      • output of a strace command of a Jenkins process that appears in previous screenshot (all Jenkins process have same strace output)

      I don't manage to isolate a faultly action that cause this issue. Sometime it's during a build, sometime it's just when I click to save a configuration modification of a job... Each time issue appears suddenly.

      Ask for precision, and very sorry for my English...

      Best regards.
