Possible Memory Leak in StoredFieldsWriter
------------------------------------------
Key: LUCENE-2283
URL: https://issues.apache.org/jira/browse/LUCENE-2283
Project: Lucene - Java
Issue Type: Bug
Affects Versions: 2.4.1
Reporter: Tim Smith
StoredFieldsWriter creates a pool of PerDoc instances
this pool will grow but never be reclaimed by any mechanism
furthermore, each PerDoc instance contains a RAMFile.
this RAMFile will also never be truncated (and will only ever grow) (as far as
i can tell)
When feeding documents with large number of stored fields (or one large
dominating stored field) this can result in memory being consumed in the
RAMFile but never reclaimed. Eventually, each pooled PerDoc could grow very
large, even if large documents are rare.
Seems like there should be some attempt to reclaim memory from the PerDoc[]
instance pool (or otherwise limit the size of RAMFiles that are cached) etc
