[anthonyinit]

Hi all,
I'm having error log with this error "mod_fcgid: can't apply process slot for /home/MY DOMAIN/fcgi-bin/php5.fcgi"

Server running process became 400+ Ram used 1.4GB out of 2GB

VPS with Virtualmin Control Panel
Debian OS
2GB RAM

Please help me here.

It looks like you're using FastCGI as your PHP handler, which by default has some pretty low limits associated with it, especially for MaxProcessCount. Since you're on a VPS you can bump up the defaults a bit to allow more concurrent PHP processes to run at once, and stop these types of errors from happening.

You might want to ask your host about this depending on how they have things configured for you. In my case the default settings for FastCGI are adjusted here:

/usr/local/apache/conf/php.conf

Here are the settings I've been using that seem to work in most cases:

# Fastcgi configuration for PHP5
LoadModule fcgid_module modules/mod_fcgid.so
MaxRequestsPerProcess 500
MaxProcessCount 3
MaxRequestLen 33554432
IPCCommTimeout 60
IdleTimeout 120
IdleScanInterval 30
BusyTimeout 120
BusyScanInterval 90
ErrorScanInterval 3
ZombieScanInterval 3
ProcessLifeTime 3600

If it's not your FastCGI limits that are causing these errors, I've also seen it where you need to correct permissions to (755) on the log directory FastCGI tries to use. I think in your case that'd be /var/log/virtualmin/, other common places to check would be /var/log/httpd and /usr/local/apache/logs/.

Hope that helps, good luck.

Hi Jacob, Thank you so much for replying,
actually i try to find /usr/local/apache/conf/php.conf but i couldn't find apache directory in usr/local

for your 2nd option yes i have already change directory permission to 755 but still i face the same problem so i want to try your 1st option yet i couldn't find the file php.conf on ubuntu using apache2 / php5

Thank you

is there anything to edit here?
/etc/apache2/mods-available/fcgid.conf

Hello Anthony,

No problem at all for the help.

Yes it does look like in your case you'd need to modify that file more than likely:

/etc/apache2/mods-available/fcgid.conf

Another way to check is by taking a look at the includes in your Apache httpd.conf file. If you don't know the location on your server you should be able to use:

locate httpd.conf

It will typically be in a .../apache/conf/httpd.conf location. Once you find the file run:

grep Include /usr/local/apache/conf/httpd.conf

That will spit back all your Apache includes, more than likely you'll see the path to your fcgid.conf there, confirming that configuration is getting applied into Apache.

You might have something currently along the lines of:

<IfModule mod_fcgid.c>
  AddHandler    fcgid-script .fcgi
  FcgidConnectTimeout 20
</IfModule>

Below your AddHandler line, is where you can set all the settings for FastCGI. Just use the same rules I mentioned before, you probably don't need to use all of them, as that errors is typically just from the MaxProcessCount 3 rule not being there. However in my experience the other settings are also helpful from a maximizing performance, and reducing errors standpoint for FastCGI. Since for instance without the MaxRequestLen 33554432 being set, you could encounter upload errors from your PHP scripts.

Let me know if that did the trick for you.

Hi again Jacob,
my httpd.conf also located in the same directory

/etc/apache2

but there is nothing on the file it is blank, however apache2.conf has many details

in my fcgid.conf file i see exactly same thing u mention

<IfModule mod_fcgid.c>
AddHandler fcgid-script .fcgi
FcgidConnectTimeout 20
</IfModule>

so i edit that file and add what you mansion before now it looks like this

<IfModule mod_fcgid.c>
AddHandler fcgid-script .fcgi
FcgidConnectTimeout 20
MaxProcessCount 3
MaxRequestLen 33554432
</IfModule>

hope this way is correct, i don't have much experience on these things and my server is unmanaged. one more thing about a week ago i contacted my hosting company and seek their help and they told me that my issue is more likely FcgidMaxProcesses and FcgidMaxRequestLen exact the same thing you mention but i didn't know how and where to edit this but thanks to you now i know which file to edit, now that i edit these value i should give sometime and see if this will fix my issue and i will keep you posted

once i thank you so much for your support.

Hey anthonyinit,

Awesome! No problem at all, I know that's a frustrating problem to deal with, so glad to hear that worked for you.

I've had countless VPS customers that I've had to do these steps for on our own cPanel/CentOS servers where I work <<snipped>> Thanks for getting back to me and letting me know the same tactics appear to work elsewhere as well

Hope things keep chugging along nicely for you!
