Worker with pid 53 was terminated due to signal 9

I recently moved my django site from Heroku to Render as a Web Service. I’m on the free tier, and I notice the website is very slow and unreliable. I never had these issues on Heroku. I’m not sure what the resource differences are, and I understand that this is a free tier, so I shouldn’t expect much, but I can’t figure out how I can speed things up.

Sometimes, the site loads. But, unpredictably, the site will show a black screen that says “EOF”.

When I check the logs, I see:

I’m not sure what /favicon.ico is, since it’s nowhere in my codebase.

Any advice?
(also I releaize how difficult it is without knowing what the backend of my site is actually doing).

I switched to using https://railway.app/ to deploy my website… it’s super quick. Zero issues. And free. Am I doing something wrong on render?

Browsers will commonly make requests to /favicon.ico as it’s become a standard for favourite icons.

I’m able to load https://doritostats-72na.onrender.com/fantasy_stats/league/2022/1086064/ without issue.

Does the EOF occur for any given scenario? From some Googling, gunicon and signal 9 might be a result of running out of memory perhaps?

As you note, our free tier does have limited resources.
