Tilman Hausherr updated PDFBOX-5372:
------------------------------------
Affects Version/s: 2.0.25
> *LOADS of* "WARNING: key node000xxxxx already exists in destination IDTree"
> ---------------------------------------------------------------------------
>
> Key: PDFBOX-5372
> URL: https://issues.apache.org/jira/browse/PDFBOX-5372
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.25
> Reporter: nunop5
> Priority: Major
>
> Hello,
> I've been using PDFBox since very very long, and it's been working very well 👍
>
> However, for 2 sets of PDFs I'm trying to merge in the past day, for some
> reason I'm always getting LOADS of these Warnings, with a "out of memory"
> crash at the end.
> I believe (but could be wrong) that the "out of memory" is due to these
> endless Warnings.
> (heap is currently 15g)
>
> But, does anyone know what could be causing these warnings? (anything in
> specific you'd suggest me to look at, in these PDFs?)
>
> Thank you very much!
>
> (... LOADS of these, redacted ...)
