What version of Go are you using (go version)?

go version go1.14.6 gccgo (GCC) 10.4.0 solaris/sparc64

Does this issue reproduce with the latest release?

Don't know.

What did you do?

gccgo built application sometimes ends with:

fatal error: schedule: spinning with local work

https://github.com/golang/go/blob/master/src/runtime/proc.go#L3338

Any comment or suggestion how to debug it is welcome!

That clearly shouldn't happen. It's worth trying a newer version (I believe the current version is 12.2).

I'm not sure what to suggest for debugging this. You could start by editing the code to print out information about the goroutines on the local run queue. Then try to figure out how they got there.

I really don't know what is going on here, sorry. Is it possible to share code that can be used to reproduce the problem?

I don't have myself access to problematic app. I was just told that the problem appears about once per two days.
