Start with patzilla/access/uspto/pdf.py at the requests.get call shown in the traceback, then read patzilla/access/generic/pdf.py around pdf_universal_real to understand how failures affect callers and resource use. Check the existing tests for USPTO PDF fetching and error handling. Done means repeated connection timeouts no longer leave the web server unresponsive, with the intended behavior for this unavailable source made clear.

Descrizione

Problem

The system is experiencing those errors which apparently lead to resource consumption that makes the web server no longer respond to any requests after a few iterations. Why?

Thoughts

We probably need to turn off this subsystem so it no longer causes any troubles? Or improve error handling at this spot? Or try to switch to another data source URL, if there is any?
