Unexpected drop in filter cache size

(Val Vakar) #1

I'm monitoring ES using bigdesk and under heavy load I noticed the filter
and field caches sometimes dramatically drop in size (by 90% or so). Cache
evictions are reported as 0.
There's plenty of free RAM and the cache size is nowhere near the
configured limit.

My main concern is that I may have lost a lot of the cached values.
