std::bad_alloc error

[dreram]

I keep getting this memory error for bad_alloc. THis occurs at random for the same file at random times. For the same file, it occurs some times and does not occur some other times. I am runng docling -v -vv input.pdf outputDir

Here is a part of the error messages I am getting:

Is there some setting that can be altered for this to be corrected?

@dreram can you please provide the output of docling --version and the example file which generates the error?

Thank you for the update.
Here is the verison output. Is there any other log settings that can be changed to create more granular logs that might be of help?

(venv) PS C:\projects\pythonServices\pdfService> docling --version
Docling version: 2.113.0
Docling Core version: 2.86.0
Docling IBM Models version: 3.13.3
Docling Parse version: 7.7.0
Python: cpython-314 (3.14.6)
Platform: Windows-11-10.0.26200-SP0

Explanation:
the error occurs often and randomly. Once one file fails like this, all other attempts at other files also fails with the same error. At times I have a whole batch working perfectly well, and then there are times when the exact same batch of files fails with the same std::bad_alloc error. So it does not matter which file I use. I was able to parse this without errors a few times, but then now it fails most of the time.

Any advise on how to automate this, for example from java spring boot back end.

Thanks
