Docker, system limits and reverse proxies.

Mara Voss covers the systems layer: Docker daemon failures, Linux resource limits and file descriptors, exec and shebang problems, OpenSSL provider changes, and the proxy errors (499, socket hangs, unexpected EOF) that appear between a client and an origin.

Method: limits are measured with the runtime that hits them, and every suggestion comes with the command that shows whether it worked. Distribution-specific behaviour is labelled as such instead of being generalised.
