Converter seems to get stuck on very large pdfs

### Bug
When trying to parse very large pdf files (such as [this one](https://dserver.bundestag.de/brd/2024/0350-24.pdf) with over 3000 pages, the converter seems to get stuck. For instance, a 300 page pdf with similar content may take anywhere from 10 to 20 minutes on my system, but the 3000+ page file above did not finish converting even after 8 hours.

### Steps to reproduce
```python
pipeline_options = PdfPipelineOptions()
pipeline_options.do_ocr = True
pipeline_options.do_table_structure = True
pipeline_options.table_structure_options.do_cell_matching = True

converter = DocumentConverter(
format_options={
InputFormat.PDF: PdfFormatOption(
pipeline_options=pipeline_options, backend=PyPdfiumDocumentBackend
)
}
)
converter.convert("https://dserver.bundestag.de/brd/2024/0350-24.pdf")

```
