Images won't load via Wikimedia images proxy #405

Closed acka47 closed 3 months ago

acka47 commented 3 months ago

We had this before (#291) but as this seems to be different, I am opening another issue.

Images won't load and the page seems to be in a perpetual loading state because of failing to load the image. Firefox dev tools do not really give back an error message or even the request. Example: https://lobid.org/gnd/119560275

From /var/log/php7.4-fpm.log:

[22-Aug-2024 15:17:39] WARNING: [pool www] server reached pm.max_children setting (37), consider raising it

Raising the limit to 50 in /etc/php/7.4/fpm/pool.d/www.conf fixes the script for now. Need to investigate these pool settings further.

With

8GB RAM available in total and
50 max child process x approx. 18 MB each child process = approx. 900 MB

this limit seems to be save. We could even set a higher limit if needed. Closing.
