 * Hi,
 * I have centos 6.3 on 16GB/4 vCores Virtual Server (hosteurope.de). I’m having
   currently 3 domains (2 wordpress, 1 drupal). The last few days I receive a lot
   internal server errors especially on high traffic and I’ve been trying to find
   out the root of the problem. The main error I receive is in /var/log/httpd/error_log:
 *     ```
       [some_date] [warn] mod_fcgid: process 13442 graceful kill fail, sending SIGKILL
       [a_date] [error] FastCGI process 32657 still did not exit, terminating forcefully
       [a_date] [warn] mod_fcgid: cleanup zombie process 18283
       [a_date] [warn] (105)No buffer space available: connect to listener on 0.0.0.0:80
       ```
   
 * In the logs of each website I have also:
 *     ```
       domain1 (wordpress), /var/www/vhosts/domain1/logs
       [a_date] [warn] [client an_ip] mod_fcgid: read data timeout in 70 seconds, referer: myrurl
       [a_date] [warn] [client an_ip] mod_fcgid: stderr: \t\t\t\tORDER BY dp_date DESC, cntaccess DESC
       [a_date] [warn] [client an_ip] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
       [a_date] [error] [client an_ip] Premature end of script headers: wp-cron.php
       [a_date] [warn] [client an_ip] (70007)The timeout specified has expired: mod_fcgid: can't get data from http client, referer: a_url
       ```
   
 * domain2 (wordpress), /var/www/vhosts/domain2/logs
 *     ```
       [a_date] [error] [client an_ip] Premature end of script headers: wp-comments-post.php, referer: a_url
       [a_date] [error] [client an_ip] Premature end of script headers: index.php, referer: a_url
       [a_date] [warn] [client an_ip] mod_fcgid: read data timeout in 70 seconds
       [a_date] [error] [client an_ip] Premature end of script headers: index.php
       ```
   
 * domain3 (drupal) /var/www/vhosts/domain3/logs
 *     ```
       [a_date] [warn] [client an_ip] mod_fcgid: stderr: PHP Warning:  Maximum number of allowable file uploads has been exceeded in Unknown on line 0, referer: a_url
       [a_date] [warn] [client an_ip] mod_fcgid: read data timeout in 70 seconds, referer: a_url
       [a_date] [error] [client an_ip] Premature end of script headers: index.php, referer: a_url
       ```
   
 * I was checking around at the beginning how I could handle with the error of the
   mod_fcgid and I found some answers like increasing some parameters in /var/etc/
   httpd/fcgid.conf, i.e.
 *     ```
       FcgidIdleTimeout 40->3600
       FcgidProcessLifeTime 30->7200
       FcgidMaxProcesses 40->64
       FcgidMaxProcessesPerClass 8
       FcgidMinProcessesPerClass 0
       FcgidConnectTimeout 30->300
       FcgidIOTimeout 70->7200
       FcgidInitialEnv RAILS_ENV production
       FcgidIdleScanInterval 10
       IPCCommTimeout  7200
       IPCConnectTimeout 180
       ```
   
 * This has improved just the occurrence of the errors of mod_fcgi but especially
   on high load there is a lot of latency especially when somebody submits a comment
   or edit a page.
 * As a consequence I tried to check whether there is any problem on the performance
   of the server or something wrong in the website. I tried to check the CPU usage
   for each website and I found out through top -c that there is high usage (30-
   100%) on php-cgi processes, especially on the websites that are related to wordpress,
   i.e.
 *     ```
       /usr/bin/php-cgi -c /var/www/vhosts/system/domain1/etc/php.ini
       /usr/bin/php-cgi -c /var/www/vhosts/system/domain2/etc/php.ini
       ```
   
 * It seems that there is something wrong with some php script. However I don’t 
   know how I could limit the possibilities of the error and actually find what 
   is creating so much load. Any ideas?
 * Thanks in advance
