How do I troubleshoot LRU caching issues?

I'm having issues with my LRU caching implementation. It doesn't seem to evict the least recently used items.

Let's start by checking your cache size configuration. What size have you set for your LRU cache?

I've set it to 100 items, but it still keeps all items in memory.

It sounds like there might be a problem with the eviction logic. Can you share how you're implementing the eviction process?

I'm using a linked list to track the order of usage, but it doesn't seem to update correctly.

Make sure that you're updating the linked list whenever an item is accessed. If the list isn't updated, it won't evict the correct item.
