FreePBX Distro 13.0.192.9 with Asterisk 13.12.2 load of about 100 concurrent calls I am getting sporadic choppy audio for a few seconds that is time coinicident with these CLI debug :

When I look at timing sources:

Module                         Description                              Use Count  Status      Support Level
res_timing_dahdi.so            DAHDI Timing Interface                   0          Running              core
res_timing_pthread.so          pthread Timing Interface                 0          Running          extended
res_timing_timerfd.so          Timerfd Timing Interface                 26         Running              core

I see res_timing_dahdi.so is not used. But when I run dahdi_test I average 99.97%.

Should I noload the other two timing modules? Has anyone else seen this issue? It started after my last batch of updates.

I fixed the issue by entering

  noload=res_timing_pthread.so
  noload=res_timing_timerfd.so

in /etc/asterisk/modules.conf and restarting asterisk.

So only res_timing_dahdi.so is loaded and the audio problem is fixed. I hope this doesn’t break something else.
