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.
