What did you expect to see?

I expect os.RemoveAll to delete all the files

Sometimes the dir is not deleted and then an error is thrown.

Thanks!

Can you please include a runnable code sample that demonstrates the issue. Thank you.

Is it possible that some other goroutine, or some other process, is creating entries in the directory as you are trying to delete it?

@ianlancetaylor you are true, I just found this problem, Thanks. Another process is using this dir. I delete this directory for the purpose of letting the program exit. When os.RemoveAll remove all other files in this dir and will exec Remove(path)， the process creates a new file in this dir to cause this error.
@davecheney @ianlancetaylor Thanks.
