Tim Allison commented on TIKA-3823:
-----------------------------------
bq. not sure about the uncompressed size.
This is not the same as uncompressed size, but you can try opening the file in
MSWord or Open/LibreOffice and saving as text.
There's not much we can do without the test file.
I would recommend trying to run a more recent version of tika against the file,
say {{java -jar tika-app-2.4.1.jar -Xmx2g yourfile.doc}} and seeing if you
still get an oom.

> Project: Tika
> Issue Type: Bug
> Affects Versions: 1.23
> Reporter: earl
> Priority: Blocker
>
> OutOfMemoryError occurs while parsing a doc file of size 450 MB, not sure
> about the uncompressed size. While analyzing the heap dump, the thread that
> parses that file has a byte array of size around 450 MB. The heap size is set
> to 2 GB still this issue persists.
