I see noting abnormail in the logs though the system becomes unstable quite quickly as the Nginx worker(s) onper core each consume the cpu.

I am thinking its a bug and I wa working on rebuilding the new container. But I can help test before I decom the server if it is useful.

proxy_max_temp_file_size 0; client_body_buffer_size 0; client_max_body_size 0; proxy_buffering off; proxy_request_buffering off;

This is the custom config on a number of sites I am running

I uncovered the issues as I thought it was with an advanced config. Once I cleaned up a few issues there I was able to upgrade without issue.

Getting similar issues. At first thought I was getting spammed with bots but with no external rules forwarding I'm still seeing maxed CPU usage.
