[ Nextcloud ] Last update php-fpm high number of threads #192
Open
Description
Hi,
Since today, my server faced a really high load average :
root@aragog:# top -b -n 1 | head
top - 18:36:02 up 2:13, 1 user, load average: **17,00, 15,81, 11,89**
Tasks: 222 total, 1 running, 221 sleeping, 0 stopped, 0 zombie
%Cpu(s): 1,5 us, 0,4 sy, 0,0 ni, **96,4 id**, 1,7 wa, 0,0 hi, 0,1 si, 0,0 st

1 root 20 0 29416 5200 3100 S 0,0 0,1 0:00.69 systemd
While throubleshooting, I noticed that :
1/ My CPUs were idle
2/ There was a large number of php-fpm processes in nextcloud's container :
/ # ps auxf
PID USER TIME COMMAND

153 1000 0:00 php-fpm: pool www
154 1000 0:00 php-fpm: pool www
(I only have 2 cores on this server)
Looking at php-fpm's conf, I noticed that :
/ # cat /php/etc/php-fpm.conf
[global]
daemonize = no
error_log = /php/logs/error.log
[www]
listen = /php/run/php-fpm.sock
pm = dynamic
pm.max_children = **15**
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 6
chdir = /
request_terminate_timeout = 0
env[PATH] = /usr/local/bin:/usr/bin:/bin
php_admin_value[post_max_size] = 30G
php_admin_value[upload_max_filesize] = 30G
php_admin_value[max_execution_time] = 10800
php_admin_value[max_input_time] = 3600
php_admin_value[expose_php] = Off
php_admin_value[memory_limit] = 512M
php_admin_value[session.save_path] = "/php/session"
I changed "15" by "2", restarted the container and everything went fine.
Will you please update your image or do I have to share php-fpm.conf with my host in order to keep the good setting ?
Regards,
z.
