We are running FreePBX 13.0.194.5
NAT = Yes, Static IP
We are experiencing lots of very high active calls anywhere from over a hundred to several hundred. This is displayed from the dashboard when looking at the statistics.
When looking at the full log file I see lots of the following:
[2018-04-16 08:41:26] DEBUG[35033][C-0000033e] format_wav.c: Skipping unknown block ‘LIST’

Other symptoms we are seeing is when you place a call from the outside to the PBX, I hear the bleep and then a long period of silence and then eventually I hear the IVR announcement play.
When transferring a call, there is a long delay in the pickup.
This is a system that has been running very stable for quite some time. Two things have recently changed. We recently installed the datadog-agent v6 but we have since removed that agent. The other is that we moved the cdr and cel tables to another folder with more disk space. I had initially created a symlink to the whole directory but that apparently according to some docs I read was not a good thing to do. I have since put the .FMT files back to where they were and only symlinked the MYI and MYD files and initially that seemed to make everything run fine. After a couple days though, we are experiencing the issue again. I have checked the tables by running “check table cdr” and “check table cel” and they show as OK.
Additionally, when I reboot the server, asterisk will not start. I have to start it manually by using “service asterisk start” and then it starts fine. Here are some of the logs I found after restarting.

If you want to use “service asterisk start” or perhaps “systemctl start asterisk” if using systemd , you need to make sure that the AST_USER and AST_GROUP are “asterisk”. For redhat and that will be defined in /etc/sysconfig/asterisk in debian that would be in “/etc/default asterisk” , either recipe should be able to start asterisk properly as a system service.
