Error writing to timing pipe: Broken pipe

[dcollinsLMC]

After upgrading to OS X High Sierra and Asterisk 15.1.5, I am getting an error after the system is up and running for about 10 seconds. It is: [Dec 17 09:45:08] ERROR[16643]: res_timing_pthread.c:355 void signal_pipe(struct pthread_timer *): Error writing to timing pipe: Broken pipe.

printing at about 20 times a second, non-stop. Still, the phone system seems to be working fine, but crashes after a day or so I assume due to the huge log file.

Also, does not seem to be respecting -q (quiet mode) on startup, nor have I found any way to stop this message from printing..

Does anyone have any idea what the underlying cause might be? or a way to get it to stop logging? I have looked over configuration file examples to see if I could find any difference that might be causing this (I am using my old SIP and extensions config files) but I cant find anything

Following up on some initialization warning messages, replaced deprecated "username" with "defaultuser" and that seems to have fixed the problem
