Tried to reproduce this bug by modifying api_worker in tacker.conf file.

First checked for api_workers = 4, and got the below workers started successfully:

So api_worker is working fine. But little bit confused about the number of active workers.
For api_workers=4 it is showing approx 17 active workers and for api_worker=2 it is showing 7 active worker.
If anyone elaborate, it will be helpful.
