FastCGI (mod_fcgid: process /var/www/cgi-bin/cgi_wrapper/cgi_wrapper)

[DannyM]

Hello,

I am running Plesk 10 for Linux and due to it being almost an obligation to parse PHP using FastCGI when running Joomla instances on Plesk (for security/ownership issues), I need to find out how to properly configure FastCGI.

Currently, i'm not sure if some of my issues are caused by faulty coding or if they are caused by some ressource (PHP/FastCGI) configuration ? A specifig error I get when running a Joomla component is a internal server error 500 which is specifically detailed (in the error_log) as "mod_fcgid: process /var/www/cgi-bin/cgi_wrapper/cgi_wrapper(18098) exit(communication error), get unexpected signal 11".

I cannot find much on the Web about this and what I can find points to either PHP/FastCGI configurations or bad coding ?

Any thoughts would be greatly appreciated ?

Thanks!

Yes, I have the same problem using Plesk 10.3 for Linux - CentOS 5.6

[error] mod_fcgid: process /var/www/cgi-bin/cgi_wrapper/cgi_wrapper(21519) exit(communication error), get unexpected signal 6

I was told from the Hosting Support that eventually the session.save_path needs to be fixed.

hi

these r different erros, cause signal 11 means segmentation fault and signal 6 stands for signal abort.

on signal 11 you should check your memory. also you should enable core dumps to find out, why mod_fcgi was
failing.

we had a related problem, which has to do with strange behaviour of a library used for imap.

can you tell us, what the joomla had done before the segfault occured?

Hi Pat,

no Joomla installation in this case. We programmed the sites with CAKEPHP http://cakephp.org/

However I could solve the issue by accident. I upgraded PHP 5.1 to PHP 5.2.10 and this seemed to have resetted some bad configured settings and then suddenly FastCGI worked again without any errors.

Hope this helps.

Greets,

John

ah ok

sorry for joomla, i think i had mixed some threads in my brain

good luck with fcgi. if you encounter the segfault again, then you should provide the core dump here.

jeje ) Will do will do. I personally also don't like those threads where some suddenly found the solution to the problem but doesn't publishes it
