: To tweak our scoring, a custom hit collector in SolrIndexSearcher creates 1 : fieldCache and 3 ValueSources from 3 fields: : - an integer field with many unique values (order 10^4) : - another integer field with many unique values (order 10^4) : - an integer field with hundreds of unique values
so you customized SolrIndexSearcher? ... is it possible you have a memory leak in that code? If you have all of your cache sizes set to zero, you should be able to start up the server, hit it with a bunch of queries, then trigger a commit and see your heap usage drop significantly. ... if you do that over and over again and see the heap usage grow and grow, there may be something else going on in those changes of yours. -Hoss
