I have  
`indices.fielddata.cache.size: 60%` in my elasticsearch.yml.

Right now when I look `/_nodes/stats/indices/fielddata?fields=*` I see that `indices.fielddata.memory_size_in_bytes` has my nodes taking up more than 70% of the heap but my evictions is 0.

Shouldn't I be seeing evictions? and shouldn't the percentage be less than 60%?

Thanks,kick in?
