java.lang.OutOfMemoryError: Java heap space

Hi,

We are using spire.pdf version 8.11.8. For some PDF's we get an OOM with the following stacktrace:

java.lang.OutOfMemoryError: Java heap space

It is not clear to us why we get this OOM for certain PDF's. We have it for example for a PDF of size 173 KB. For other larger PDF's we don't have any problem.

Is there a way to find out what is causing the OOM by enabling for example some logging or so?

Regards,
Guy Wens

Hi,

Thanks for your inquiry.
This issue may be caused by the complexity of the document structure, could you please provide us with your test document and code to help us do a further investigation? You can send them to us via email ([email protected]) or attach them here. Thanks for your assistance. In addition, this problem occurs when our Spire.PDF processes documents, I am afraid that it can’t be logged.

Sincerely,
Triste
