Time to wake up the dead thread 
same behaviour here after some time (hours).
Any idea ?
Tip : systemctl restart rh-php56-php-fpm helps. Must be some timeout issue.

I believe that the core issue here is linked to that error message that appears each time the server hangs :
[19-Aug-2019 18:51:03] WARNING: [pool fpbx] server reached pm.max_children setting (50), consider raising it
Who is the main developper of that module ?
I think it’s @Stll0 (Contributors to NethServer/nethserver-freepbx · GitHub) 
But freepbx is an admin application, I’ve never seen reaching the FPM children limit.
Are you sure you are not under a DOS attack or similar?
I hope so since its listening on green interface
Of course I see the usual script kiddies trying to get a line on asterisk’s log but it should not trigger anything on the fbpx side I guess.
Scratch this. It crashed again but without any error message in the log file. Very strange.
