It's very difficult for us to investigate reports of memory leaks without any sort of example.

At the very least, we need much more information about what code paths to check: OS, system or custom allocator, HTTP 1 or 2, TLS (and which one) or not, middleware used, other notable features used, other crates used, how many req/s does this server deal with?

Even better if you're not able to provide the code would be if you are able to profile the allocations yourself.

This could be the same memory issue that I casually mentioned in #1607 yesterday.

I've just made 100,000,000 requests with 200 concurrent connections against the root endpoint in my example. The memory consumption was less than 500KB at the beginning, after the benchmark was finished it was almost 800MB.

I'm still a Rust newbie, but if I can help in any way, for example further testing, let me know.
