Hello,

   Past 2 months we were getting below error while deleting any PR's, builds, jobs, folders. Since none of the jobs are getting deleted Jenkins Master is constantly running out of space.

Looks like "org.marvelution.jji.SitesClient" is causing an issue during the delete process and Jenkins is throwing the below error.

A problem occurred while processing the request.

Logging ID=1969213f-374a-4e6d-9507-c0c9798e0f0a
