You said: "It happened to work on same config test machine but not working in production." and "How can I debug this behavior?"
  1. Determine the difference(s) between your Production machine and your test machine.
  2. Correct the setup of the test machine to accurately reflect the Production world.
  3. Debug your code on the test machine using your normal tools.
  4. Deploy to production and observe the results.
