Tim Allison commented on TIKA-2847:
-----------------------------------
The main {{document.xml}} decompresses to ~100MB...which is not insignificant.
Our standard docx parser relies on xmlbeans and DOM and is not the most memory
efficient.
I was hoping switching to a more recent version of Tika that bundles xerces2
would help, and it didn't. I still hit OOM at -Xmx512m.
When I switched to our SAX based docx parser, though, I was able to parse it
with -Xmx64m. See the documentation
(https://wiki.apache.org/tika/MSOfficeParsers) for how to configure Tika to use
the streaming docx parser.
Let us know if you have any questions.

> I am trying to parse a docx file and getting below error. Same issue happens
> if i convert attached docx file to a pdf.
> Attached pdf file is of 3.7 mb, however i doubt it is related to size of the
> file, as i am able to parse a file above 30mb without any issues.
> PS : This issue only happens if we have JVM configured to -Xmx512m if i
> change value to 1024m it starts working fine.
