Web app not available "- *** uWSGI listen queue of socket ":8000" (fd: 4) full !!! (101/100) ***"

[fnielsen]

Describe the bug
Web app not available, - or very slow.

To Reproduce
Steps to reproduce the behavior:

1. Any access to https://scholia.toolforge.org/
2. No response
3. In the log: - *** uWSGI listen queue of socket ":8000" (fd: 4) full !!! (101/100) ***

Expected behavior
The web app should return a page

Additional context
In the log there is a few /doi/... entries. Perhaps the blocking request is what causes the problem.

• Investigate the timing of DOI response
• Perhaps it would be better to use the Wikidata API rather than the WDQS for DOI lookup.
• The doi aspect could be shut down!?
