@miguel thank you for your input.
There is clearly something happening that will not even allow ping (icmp) to go through. Up to some seconds of downtime. I have addressed this before as well since this can be a big issue on many installations out there.
You could do a remote session if you want to see what is happening there since this will not effect new small installations much but as soon as you have some extensions, routes and so on the downtime will extend. Even if you have the best hardware in the world.
There is clearly something different happening then like in the Web-Gui apply changes.
Maybe if we can not find a solution for the “apply ALL changes” we could have a way to apply certain modules through the API?
Please help accordingly. Thanks.
EDIT, here we go:
firewalld is involved somehow on the “apply changes” API. This will cause the dropouts.
dump_asterisk_c is only at 10% CPU. firewalld at 11%.
After everything is done firewalld is not even found anywhere in TOP. So consuming almost none CPU anymore. Hope this helps finding this.
507 root 20 0 408728 71304 4224 S 11,0 7,0 2:54.73 firewalld
25483 root 20 0 364004 42892 12404 S 10,3 4,2 0:01.31 dump_asterisk_c
Edit2:
When Firewall is disabled, this problem does not happen.
