Nutrition stats for categories are not shown anymore

[stephanegigandet]

What

• We used to display nutrition stats for categories on category pages (e.g. https://world.openfoodfacts.org/category/cakes ) and in the nutrition facts table of individual products.
• They are not shown anymore.

To Reproduce

https://world.openfoodfacts.org/category/cakes

Expected behavior

Nutrition stats for the category should be displayed.

This is due to a mongodb timeout when generating stats:

completed products: 68100
completed products: 68110
[Tue Jan  4 17:44:07 2022] gen_top_tags_per_country.pl: MongoDB::DatabaseError: operation exceeded time limit

In fact in production this script has failed since April 2021:

-rw-r--r-- 1 off users 24 Apr 19 2021 categories_nutriments_per_country.mo.sto
-rw-r--r-- 1 off users 24 Apr 19 2021 categories_nutriments_per_country.hn.sto
-rw-r--r-- 1 off users 374175 Apr 19 2021 categories_nutriments_per_country.th.sto
stephane@off1:/srv/off/scripts/equadis-import$ ls -lrt /srv/off/index/

The problem shows now because we moved the location of the generated files to /srv/off/data/ ... and they are not generated.
