If you have a product from CloudBees, then you’ll usually get the best answers by opening a question through the CloudBees support system.
There isn’t a product called “CloudBees Jenkins”, so I’m not sure what you have. If you have Jenkins, then it is not a CloudBees product. If you have CloudBees CI, then that is a CloudBees product and the CloudBees support team is your best choice.
That may mean your agents are running on a remote file system and the remote file system is heavily loaded. Either use a local file system (preferred) or increase the check interval with that setting.
