regarding unbound library

Unbound
1

Hi Team,

I am using unbound package in my project. I am facing one issue at customer place. We have used asynchronous unbound calls,

Below is the code snippet.

  1. count = 0
  2. while (status == 0) and (not my_data[‘done_flag’]):
  3. val = ctx.poll()
  4. if val:
  5. status = ctx.process()
  6. coro.sleep_relative(0.1)
  7. count = count + 1
  8. #30 seconds timeout value is set
  9. if count > 300:
  10. self.dnssec_del()
  11. raise DNSSEC_Error(qname, qtype, resolver, \
  12. “SERVER TIMEOUT”)

Below are the errors observed at customer place.
