Override golang profile stop in case of interrupt

When I kill -SIGINT pid on my Golang service I have a graceful shutdown where I call the profile.Stop, but before I could call it I got this message: profile: caught interrupt, stopping profiles

I can't even call the profile.Stop because it's triggered sooner, however the grpc listen and couchbase connection shutdowns works properly.

Is there anyway I can override this malfunctioning profile stop?

There is a profile.NoShutdownHook function which controls whether the profiling package should hook SIGINT, on which to write profiles cleanly.

You may use / pass the above mentioned function as an option to profile.Start() if you want to disable this behavior:

profile.Start(profile.NoShutdownHook)

Starting and stopping the profiling inside a function is best done via deferred, e.g.:

// disable the automatic shutdown hook.
defer profile.Start(profile.NoShutdownHook).Stop()

If you disable the automatic shutdown hook, make sure you call Stop() manually in your shutdown handler properly.
