[asterisk-users] Having problem getting Asterisk to work on CentOS 7

Thanks Tzafrir.

Upon further investigation it is safe_asterisk that was the process id I initially saw.  I believe this is what was installed when running make config to install the Initialization Scripts in the asterisk 13.14.0 source code
Asterisk did not start up previously on a restart.

I changed SELINUX setting in /etc/selinux/config (default was enforcing and I changed it to permissive).  After that, I was seeing the Asterisk PID.  
I didn't realize both safe_asterisk pid and asterisk pid were displaying when I executed pgrep asterisk.

Admittedly, I'm new to systemd.  I need to research it to learn what I need to do.

pkill? nice? That is not asterisk. Are you sure you got the right process? Maybe you got safe_asterisk instead? If it is safe_asterisk:

1. That script is pointless now that you have systemd. Replace it with a simple systemd unit (hint: Restart=on-failure gets you most of the way there).

Isn't there one already included with Asterisk by now?

2. Use the option -f of strace to see the exact error message. What is error status 34 of asterisk? ERANGE?
