I think this is just a tuning issue with nginx. But before I randomly tweak various buffer settings, figure I'd ask for a recommendation on what to look for.

Size on my bar at the moment:

• 639 - Total cocktails
• 377 - Total ingredients
• 169 - My shelf ingredients

If helpful, this is the nginx default.conf file:

        server {
            listen 3000 default_server;
            listen [::]:3000 default_server;
            server_name _;

            location = /favicon.ico { access_log off; log_not_found off; }
            location = /robots.txt  { access_log off; log_not_found off; }

            client_max_body_size 100M;

            # bar-assistant
            location /bar/ {
                proxy_pass http://bar-assistant-api.bar-assistant.svc:8080/;
            }

            # meilisearch
            location /search/ {
                proxy_pass http://bar-assistant-search.bar-assistant.svc:7700/;
            }

            # salt-rim
            location / {
              proxy_pass http://bar-assistant-frontend.bar-assistant.svc:8080/;
            }
        }

Don't really have any recs, seems like this happens on responses with large body content so it buffers them to temp file.

I guess you can increase buffer size since I don't think it will increase disk usage too much
