Spotting and Avoiding Heap Fragmentation in Rust Apps
I'm not sure if it's widely used, but Mesh is a C/C++ library that can recover from memory fragmentation. The YouTube video in the README is a great watch.

Bizarre memory leak caused by tokio runtime
With everyone talking about memory fragmentation, I'd like to mention Mesh, an allocator that can compact aka defrag the heap without any help from the program or compiler. Here's the talk explaining it, "Compacting the Uncompactable" by Bobby Powers.

Bizarre memory leak caused by tokio runtime
I was able to replicate the issue with the sample code, but not when using a different allocator (https://github.com/tikv/jemallocator). I understand the default allocator on Linux is malloc (https://doc.rust-lang.org/std/alloc/struct.System.html), and while looking up the differences between the two, it seems like jemalloc handles memory fragmentation much better (https://engineering.linkedin.com/blog/2021/taming-memory-fragmentation-in-venice-with-jemalloc). Maybe that's what's going on?

Maintenance status (jemallocator)
There's an actively-maintained "simplified" fork at https://github.com/tikv/jemallocator.
What are some alternatives?
When comparing Mesh and jemallocator you can also consider the following projects:

mimalloc - mimalloc is a compact general purpose allocator with excellent performance.
jemallocator - Rust allocator using jemalloc as a backend
memory - STL compatible C++ memory allocator library using a new RawAllocator concept that is similar to an Allocator but easier to use and write.
rust - Empowering everyone to build reliable and efficient software.
