---------------------------------
Summary: Memory Leak when parsing a large (110K+) number of
documents
Key: TIKA-4427
URL: https://issues.apache.org/jira/browse/TIKA-4427
Project: Tika
Issue Type: Bug
Components: core
Affects Versions: 3.2.0
Reporter: Tim Barrett
Attachments: Screenshot 2025-05-30 at 17.22.38.png, Screenshot

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.
