“ The Lua flame graph eventually located the culprit — a string-type zero value for a server weight (i.e., “0”) was inserted into the business logic’s configuration metadata, while the Lua API of OpenResty’s lua-resty-balancer library expected a numerical weight value. It thus led to infinite recursion and infinite loops.”

Nice catch. Here we see a classic runtime data type errors for OpenResty and Lua. Strict compile time error checking languages like Rust would have helped here.

Thanks for sharing
