    Hello,

    I am getting tons of these in my /var/log/php-fpm/www-error.log
    Code:
    [28-Nov-2014 16:26:40.665525] DEBUG: pid 822, fpm_pctl_perform_idle_server_maintenance(), line 362: [pool phpmyadmin] currently 0 active children, 1 spare children

    I believe it started happening after I added phpMyAdmin following phpmyadmin.sh Centmin Mod Addon and fastcgi_cache following Nginx Wordpress Configuration Examples for rewrite rules & FastCGI Caching

    Any idea what could be causing this ?

    You shouldn't be seeing debug messages (verbose logs for everything even non-errors/normal processes such as above) by default as php-fpm.conf at /usr/local/etc/php-fpm.conf has log_level = warning unless you changed it to debug.

    Ummm I don't remember changing it. May be I did that.
    Still can you give me some info about that log message?? What strange is, there is no line 362 in any of the php or nginx config file. (no file is that big)

    Changed log level to warning now.

    You can google the error message for more info ;) Basically, it's just normal internal Nginx operations which you brought to visibility by switching log_level to very verbose debug mode.
