Use pprof: https://golang.org/pkg/net/http/pprof/
Then, when it hangs, you can pull a traceback directly from your app and see which goroutine is blocked, and exactly which line of code is the cause. You can easily get stats with wget or curl: http://localhost:6060/debug/pprof/goroutine?debug=2 http://localhost:6060/debug/pprof/goroutine?debug=1 This is assuming you're listening on port 6060; it doesn't matter what port you use. Just only listen on localhost for security. All you have to do is put this in your imports: _ "net/http/pprof" And if your app is not already running a webserver you can add: go http.ListenAndServe("localhost:6060", nil) -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
