Supervisor at 100% CPU

[fliespl]

We have just noticed that supervisor master got stuck at 100%.

Any idea how can we troubleshoot it more if it's our configuration or some other issue? All jobs look like that:

[program:unitown_push_send]
command=php bin/console 'push:send' --verbose --no-debug --env=prod
directory=/var/www/vhosts/xxx/current
autostart=true
autorestart=true
startsecs=5
startretries=999999999
user=owadmin
stdout_logfile=/var/log/supervisor/xxx_push_send.log
stdout_logfile_maxbytes=50MB
redirect_stderr=true

owadmin@owuln01:~$ supervisord --version
3.3.5

owadmin@owuln01:~$ cat /etc/os-release 
PRETTY_NAME="Debian GNU/Linux 10 (buster)"
