Hi i have a weird problem with jenkins controller, every ~ 2 weeks i get like high load and high cpu usage. On 8vcpu i have 600% cpu usage and it gets my jenkins down, after restart everything works fine. Can’t find anything in logs or metrics it just says that java consume >600% of cpu, any ideas what should i check?
jenkins setup:
ver 2.504.2
vm controller: 8vcpu 12gb ram, all of my agents are running on kubernetes cluster outside of vm that runs controller

I’d suggest trying How to identify a thread leak issue?

And also to update your Jenkins version, 2.504.2 has been published in May 2025, your issue has probably been fixed since.
