Modfcgid: can't apply process slot. My new server is a new ISPCOnfig 3.1 Debian 9 server with Apache 2.4, which means I have to use the new notation.
Description: | Provides for execution of FastCGI applications |
---|---|
Status: | External |
Module Identifier: | fcgid_module |
Source File: | mod_fcgid.c |
Compatibility: | Apache 2.0 and higher |
Summary
Apache Mod_fcgid Can't Apply Process Slot For Real
Any program assigned to the handler
fcgid-script
is processed using the FastCGI protocol; mod_fcgid
starts a sufficient number instances of the program to handle concurrent requests, and these programs remain running to handle further incoming requests. This is significantly faster than using the default mod_cgi or mod_cgid modules to launch the program upon each request. However, the programs invoked by mod_fcgid
continue to consume resources, so the administrator must weigh the impact of invoking a particular program once per request against the resources required to leave a sufficient number of instances running continuously.The pool of fcgid-invoked programs is shared between all httpd workers. Configuration directives below let the administrator tune the number of instances of the program that will run concurrently.
- But there, I tried the Nginx web server on this Apache 2.2 server, before even trying to increase FCGI slots: Well, that was a huge fail for me, and I was following the exact same documentation you linked here.
- Modfcgid: can't apply process slot - this is Apahce+FCGI issue, and in case you have huge load it can't be solved with Apahce+FCGI. But can be solved if you switch Nngix+PHP-FPM for this site sw-engine-fpm -it's a Plesk panel service and has no any effect on clients web sites.
Specific executables are assigned this handler either by having a name containing an extension defined by the AddHandler directive, or with an override using the SetHandler directive (e.g., for all files in a specific directory such as cgi-bin).
Some changes have been made in the ASF release of mod_fcgid which can affect existing configurations. All documentation refers to new names for the directives. (The old names still work but are now deprecated.) Please read the Upgrade Notes for details.
For an introduction to using CGI scripts with Apache, see the generic tutorial on Dynamic Content with CGI.

This is going to be Parallels Plesk 12.X related. I will share some experience with Linux Plesk problems, tips and tricks.
By default, plesk is using a secured shell for executing user schedule tasks, which in my case is:
/usr/local/psa/bin/chrootsh
This could lead to some problems and cron jobs malfunctioning.
Enabling /bin/bash as as default user shell (server wide) could be done with the following command:
# /usr/local/psa/bin/server_pref –update -crontab-secure-shell /bin/bash….
If your error_log ( /var/www/vhosts/VHOSTl/logs/error_log ) , has some lines like these:
[Mon Dec 22 15:04:36 2014] [warn] [client xx.yy.xx.yy] mod_fcgid: read data timeout in 45 seconds
[Mon Dec 22 15:04:36 2014] [error] [client xx.yy.xx.yy] Premature end of script headers: index.php
[Mon Dec 22 15:04:36 2014] [error] [client xx.yy.xx.yy] Premature end of script headers: index.php
OR these:
[Tue Dec 09 15:01:24 2014] [warn] [client xx.yy.xx.yy] mod_fcgid: can’t apply process slot for /var/www/cgi-bin/cgi_wrapper/cgi_wrapper
[Tue Dec 09 15:01:36 2014] [warn] [client xx.yy.xx.yy] mod_fcgid: can’t apply process slot for /var/www/cgi-bin/cgi_wrapper/cgi_wrapper
[Tue Dec 09 15:01:44 2014] [warn] [client xx.yy.xx.yy] mod_fcgid: can’t apply process slot for /var/www/cgi-bin/cgi_wrapper/cgi_wrapper
[Tue Dec 09 15:01:36 2014] [warn] [client xx.yy.xx.yy] mod_fcgid: can’t apply process slot for /var/www/cgi-bin/cgi_wrapper/cgi_wrapper
[Tue Dec 09 15:01:44 2014] [warn] [client xx.yy.xx.yy] mod_fcgid: can’t apply process slot for /var/www/cgi-bin/cgi_wrapper/cgi_wrapper
Then you probably need to tune a little bit your default mod_fcgid configuration, which resides here:
/etc/httpd/conf.d/fcgid.conf
Here is what I add:
FcgidIOTimeout 5000
FcgidBusyTimeout 5000
FcgidBusyTimeout 5000

/etc/psa/psa.conf - Some plesk related configurations
/etc/psa/.psa.shadow – Shadow password for my sq
# /usr/local/psa/bin/admin –show-password
# mysql -uadmin -p`cat /etc/psa/.psa.shadow`
Apache Mod_fcgid Can't Apply Process Slot Form
Create custom template directory
# mkdir /usr/local/psa/admin/conf/templates/custom/domain
Copy the default template to the custom directory
# cp /usr/local/psa/admin/conf/templates/default/domain/nginxDomainVirtualHost.php /usr/local/psa/admin/conf/templates/custom/domain/
..
Now you can make some modifications on the custom “nginxDomainVirtualHost.php”
Rebuild all vhosts config
# /usr/local/psa/admin/bin/httpdmng –reconfigure-all
