When we have many pipeline build running simultaneously, we see them starting to hang, never completing or failing (screenshot attached)

In the logs it shows that it failed with the following error:

org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use staticMethod WorkflowScript __cps__6009

We're not actually calling this method anywhere, so I think it's happening within jenkins workflow framework itself:

Here's a bigger chunk of the logs of one of the failed builds:
