regarding unbound library

[SUJATHA SHANMUGAM -X (sujashan - HCL TECHNOLOGIES LIMITED at Cisco)]

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.

I need the help on this. Any help will be really appreciated.
