FCGID or PHP broken

OK, I have had a perfectly functioning ISPConfig setup running for a while.

Its based on a CentOS 6.2 vm run at Bytemark.co.uk.

I recently issued a yum install update and seem to have broken my system in a subtle way.

ISPConfig (3.0.4.6) seems to work fine.

However I am running various wordpress sites and while they deliver content, various configuration pages are broken. It seems to be related to FCGID as I get the following errors in the server log for any site

Code:

[Tue Jul 03 17:07:46 2012] [warn] [client *.*.*.*] mod_fcgid: stderr: PHP Warning:  require(): open_basedir restriction in effect. File() is not within the allowed path(s): (/var/www/clients/client5/web20/web:/var/www/clients/client5/web20/tmp:/var/www/www.clientdomain.com/web:/srv/www/clientdomain.com/web:/usr/share/php5:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin) in /var/www/clients/client5/web20/web/wp-admin/admin-header.php on line 110, referer: http://www.clientdomain.com/wp-admin/index.php

I have tried various things such as changing to CGI, Mod PHP and SU PHP but I just get a different set if errors.

I have tried editing the .php-fcgi wrapper file to eliminate openbasedir, but I think thats just a symptom as I still get the 104 errors. It is as if PHP can't read a list of some kind, as simple pages work but pages which should contain a list it items taken from the database don't

Happy to provide more info if you tell me what you need.

Linux kernel is 2.6.32.33-kvm-i386-20111128-dirty
php.i686 is 5.3.3-3.el6_2.8
httpd.i686 is 2.2.15-15.el6.centos.1


Any help gratefully received

Cheers

Checked the from /var/www/www.clientdomain.com/ and all files are owned by the correct owner group combination

Similarly in the control panel

suexec is ticked and Fast-CGI is selected as the PHP mode.

 

Further Clues

ok after more investigation I can make it work a little bit better, but I still get plenty of time outs in the admin pages.

a) I temporarily hacked /var/www/php-fcgid-scripts/xxx/.php-fcgi-starter

I set openbasedir = "none"

some configuration pages started to work.

b) I changed the timeout values as follows

Code:

        FcgidIdleTimeout 300
        FcgidProcessLifeTime 3600
        # MaxProcessCount 1000
        FcgidMinProcessesPerClass 0
        FcgidMaxProcessesPerClass 100
        FcgidConnectTimeout 20
        FcgidIOTimeout 3600
        FcgidBusyTimeout 300

previously they used older? names eg IdleTimeout

I am still getting fails on configuration pages which are extracting longer lists from MySQL

yum reports mod_fcgid

mod_fcgid.i686 2.3.7-1.el6 @epel

So did an update somehow make fcgid need different names for parameters and perhaps change openbasedir or the location of some temporary file?
