------------------------------------

>From the referenced email thread:
bq. we just deployed Solr 1.4.1 and the stats page takes over a minute to load for us as well and began causing OutOfMemory errors

It looks like the ram estimator puts every object into a map to keep track if it's been visited before - so this is definitely the source of the memory issues.
