Why would I have a low percentage of used chunks for a slab class and still be getting evictions for it?

Here is a snap shot of one of my slab class's stats (from PHPMemcachedAdmin): So what I'm confused about is why, with my used_chunks so low, am I getting

This doc says something about memcached I haven't read anywhere else: Which brings me to another point, items/chunks are not actively reclaimed/expired. Memached does not have a background thread that explicitly expires items,

Re: What does the used_chunks metric in memcached stats mean?

What does the used_chunks metric in memcached stats mean?

According to this doc used_chunks is "Number of chunks allocated to an item". What does that mean? Here are the stats for one of my slabs: Used chunks is 8 and total is 48.
