I'm not sure if there is enough info here to go off of, but thought I'd report it in case something can be derived...

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

go version go1.11 linux/amd64

Does this issue reproduce with the latest release?

Untested (I have only seen this issue once so far)

What operating system and processor architecture are you using (go env)?


What did you do?

I don't have a small reproducible example yet (I've only seen the issue once), but the output mentions grpc.
Race detection was enabled.

What did you expect to see?


What did you see instead?

I am not sure that it's a go issue. From your stacktrace i see that the problem in grpc-go. Also it's hard to guess what version of grpc-go do you use

Hi @EmpireJones,

This is very little info for anybody to debug the issue. We need instructions on how to reproduce the issue and a working code sample is preferred.

Otherwise, you will get better help in the various forums at the Questions wiki page.

ok, I'll close, as the golang error doesn't provide enough info for me to dig into further either.

grpc version appears to be at 1.16.0-dev
