Hi Mukund, Please recognize that the Source object returned by rand.NewSource is not safe for concurrent use by multiple goroutines. Look at the documentation of NewSource in package math/rand. You are defining r as a global variable and probably call pickENI() from multiple goroutines, which is running into an issue. The example program will not generate a problem, because it doesn't call pickENI() in multiple goroutines.
The easy way out is to use rand.Int63 instead of r.Int63. It uses a source that is protected against use in multiple goroutines. You might want to use Seed to prevent the generation of the same ENI in each run. Alternatively you could write a lock-protected source yourself, it shouldn't be too difficult.
