FreePBX web interface becomes unreachable

[parsam (Parsam Elizbaryan)]

I have installed FreePBX 12.0.76.2. My extensions registered to server via FreePBX UCP.
Usually everything works fine, but sometimes my FreePBX web interface becomes unavailable, extensions can’t register to FreePBX and I can’t connect to FreePBX admin page. When I connect to server through ssh I see high CPU load. To resolve the issue I restart asterisk service then apache service and then kill /var/www/html/admin/modules/dashboard/scheduler.php process.

Please help me to find cause of problem,
Thank you.

maybe you’re not the only one with this problem, I found others who report similar things

Scheduler.php stuck at 100% CPU

htop is showing /var/www/html/admin/modules/dashboard/scheduler.php using 100% cpu on one core of the eight that are available (2 CPUs, 4 cores each). This is even after an fwconsole restart and a full reboot. Not that restarting should really fix anything. I recently installed FOP2 which seems to go along with the timing of when this started but not totally sure. Here is the process info from webmin: 2066 root 00:58 crond 19999 root 22:25 CROND 20000 asterisk 22:25 /bin/sh -c [ -x /var/www…

I have not installed FOP on my FreePBX.

I am having the same issue as well. Scheduler.php is 100% (or near) cpu. Causing the system to be very sluggish. Not really finding anything int he logs yet.
