A computer program product, system, and computer implemented method for fast reuse of locking data structures prior movement of entries to a cache free list. The approach disclosed herein enables management of lock management structures. Specifically, the approaches provided herein are directed towards use of lock management structures where items are managed using at least a recycle list. A recycle list and a resource list pair associated with the recycle list are controlled using a single latch, where there are any number of buckets that each include a recycle list and a resource list pair. In addition, in some embodiments, a free list is also maintained, whereas resource lists and recycle lists have a one-to-one relationship with each other, the free list has a one-to-many relationship with the buckets and lists therein.

Processes, computer-readable media, and machines are disclosed for reducing a likelihood that active functional components fail in a computing system. An active monitoring component receives metrics associated with different active functional components of a computing system. The different active functional components contribute to different functionalities of the system. Based at least in part on the metrics associated with a particular active functional component, the active monitoring component determines that the particular active functional component has reached a likelihood of failure but has not failed. In response to determining that the particular active functional component has reached the likelihood of failure but has not failed, the active monitoring component causes a set of actions that are predicted to reduce the likelihood of failure.
