Rusty Newton commented on ASTERISK-20750:
-----------------------------------------

[Valgrind|https://wiki.asterisk.org/wiki/display/AST/Valgrind] with the callgrind option can dump out a profiling report, which could be useful to anyone looking into this issue. You may also want to consider posting any further information including dialplan (extensions.conf) in use, asterisk modules in use, any configuration changes made to Asterisk. Be sure to attach the config files and do not paste them in-line.

> 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
> bsd-cli*CLI>
