This should not be a problem in qmail-lspawn/qmail-local as their code has not been changed for years. So there should have been a breaking change i...

Some background information. I have used Debian with Asterisk for several years. Have encountered zero problems. I am now trying to setup an Asterisk on a CentOS7 box using VMWare Workstation. I am brand new to CentOS and RHEL so I may be missing something obvious. I am installing CentOS Minimal Install and Asterisk from Source. (I have installed Asterisk from Source on Debian hundreds of
