I assume pbx_spool.co uses inotify, and I have the proper files in /proc/sys/fs/inotify but don't have inotifywatch installed and it is not available through enabled freePBX distro repos.
On a working VM duplicate of the system:
[root@localhost log]# grep -r inotify *
anaconda.syslog:21:56:10,402 DEBUG kernel:SELinux: initialized (dev inotifyfs, type inotifyfs), uses genfs_contexts
cron:Oct 13 12:07:54 localhost crond[1471]: (CRON) INFO (running with inotify support)
cron-20151004:Oct 12 17:43:42 localhost crond[1448]: (CRON) INFO (running with inotify support)
cron-20151011:Oct 11 18:18:30 localhost crond[1436]: (CRON) INFO (running with inotify support)
But on the production system:
[root@freepbx-a log]# grep inotify *
anaconda.syslog:20:58:35,982 DEBUG kernel:SELinux: initialized (dev inotifyfs, type inotifyfs), uses genfs_contexts
boot.log: Starting NIC Agent Daemon (cmanicd): tail: inotify cannot be used, reverting to polling
Any idea where the disconnect may be?
