Tim Allison commented on TIKA-4427:
-----------------------------------
I merged this and cherrypicked into 3.x. Let me know if there's further work.
This changes the default behavior in that we're now refreshing the parsers
after 100 parses.
I'd like to do more analysis before we change the default behavior
further...separate ticket.

> When parsing a very large number of documents, which include a lot of eml
> files we see that
> The static field XMLReaderUtils.SAX_PARSERS is holding a massive amount of
> memory: 3.28 GB. This is a static pool of cached SAXParser instances, each of
> which is holding onto substantial amounts of memory, apparently in the
> fDocumentHandler field.
> This is a big data test we run regularly, the memory issues did not occur in
> Tika version 2.x
>
> I have attached JVM monitor screenshots.
