---------------------------------------

             Summary: res_timing_kqueue makes Asterisk use 100%  CPU
                 Key: ASTERISK-20750
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-20750
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_timing_kqueue
    Affects Versions: 11.0.1
         Environment: FreeBSD 9.0 Release (clean install just to report this bug)
            Reporter: Oleg Baranov


Asterisk works but one cpu core gets loaded 100%.
Seems easy to reproduce:
- Download and unpack Asterisk
- ./configure  (trivial, with no extra parameters)
- Enable kqueue in menuselect as mentioned in workaround ASTERISK-20749
- make ; make install; make samples
- run asterisk (no config file change required) and monitor cpu load


timing test produces strange results:

bsd-cli*CLI> timing test
Attempting to test a timer with 50 ticks per second.
Using the 'kqueue' timing module for this test.
It has been 1000 milliseconds, and we got 413145 timer ticks
