What did you do?

Run my tests with -race enabled.

What did you expect to see?

I got the following error when running my tests with -race enabled.

=== RUN   TestUpdateShardKeyRange
race: limit on 8128 simultaneously alive goroutines is exceeded, dying

When race detector crashed with more than 8128 simultaneously alive goroutines, I'd expect the runtime to print out the stacktrace of all those goroutines so I can check whether those goroutines actually suppose to be there.

What did you see instead?

Silent crash without any further info on those excessive number of goroutines.

Yes, that would be nice to have.
Fortunately, we should be getting a new race detector for 1.19 that doesn't have this limit. See #49761.
So I'm going to close this issue as unnecessary. It will be so nice to be in a world where that error just doesn't happen.
