Description:
Hello,

We have an application where we store microsoft office documents. As part of
the release management we convert the office documents to pdf with watermarks
using libreoffice.

Our observation shows that some are getting failed with heavy memory

Libreoffice crashes when the documents contains heavy images and more pages
(Ex: around 600 - 1000 pages)
I have tested both CLI and GUI. Result is same.

LibreOffice 7.4.6.2
LibreOffice 7.5.1.2

CLI Command:
/opt/libreoffice75/program/soffice --headless --convert-to
“pdf:writer_pdf_Export” --outdir /tmp 7090190.docx

Size of docx : 100MB
