A real-world walkthrough of diagnosing and fixing a Go memory leak that caused OOM crashes in a Kafka consumer service. Covers Go memory fundamentals (stack vs. heap, GC tricolor algorithm, TCMalloc-based arenas), then details two concrete fixes: using Uber's automaxprocs to correctly set GOMAXPROCS in Kubernetes containers, and using pprof heap profiling to identify two root causes — repeated time.LoadLocation disk reads fixed with sync.Once, and a memory leak in the Confluent Kafka Go library resolved by switching to the Segmentio kafka-go package, reducing memory from hundreds of MB to a stable 25 MB.

So I was listening to an episode of <a href="https://www.youtube.com/watch?v=586_BAMMOQ8" target="_blank" rel="noopener nofollow">Backend Banter</a> and they mentioned looking for memory leaks in passing (The episode was with Mitchell Hashimoto and he was talking about using Zig as opposed to Rust or Go).
I was wondering how I would approach memory leaks in Go since for my work I use a different language but in my personal projects I use Rust and Go. Rust is essentially handled already but Go was somewhat puzzling to me with the GC.
All this to say, I appreciated your post. It really opened up that side of Go to me and I will definitely look into this more.

so how do i check it? pprof ? thats is mostly right
