Goroutine Leak Profiles
By BIOS Founding Team
The Go blog published a deep-dive on the new goroutine leak profiler shipped in Go 1.27, a lightweight diagnostic tool built into runtime/pprof for finding goroutines permanently blocked in production systems.
It works by analyzing reachability through the garbage collector to flag goroutines stuck on channels or sync primitives with no path to unblocking, with real-world examples drawn from Uber, CockroachDB, etcd, and Kubernetes codebases.
