Whats odd is that as i increase the children from 2 to 4 or 6 i get the error 500 more often then with a lower number???

Any ideas?

Thanks Rob...
p.s. searching for fcgi stuff on this forum did not result in to much info, well in English anyways.. Smile

In Addition there're quiet a lot options for mod_fastcgi pls use the search function in here - you'll find a lot about that topic ...


RE: fastcgi incomplete headers issues - robmorin - 11-10-2007 06:55 AM

I am getting more and more clients telling me they are getting that dreaded error 500, is there a way to turn off fastcgi for debugging purposes without going through a whole process?

Am i the only one having these issue? I would assume others would have it to... but like i mentioned before it only seems to happen when there is a database with mysql involved, other than that the plain Jane sites are ok...

Any suggestions?

Thanks to all in advance

Rob..

robmorin to turn off fastcgi just do a2dismod fastcgi and reload your apache

RE: fastcgi incomplete headers issues - joximu - 11-11-2007 06:30 AM

maybe also a2dismod fastcgi_ispcp or similar...

that's the one Smile

but you should know that ispCP (front-end) might not work properly when fastcgi is disabled; so in any case you might want to keep fastcgi enabled for the panel

RE: fastcgi incomplete headers issues - Cube - 11-11-2007 08:47 AM

ispCP already has the mod_php sections in the config. So if the front-end would work, ispCP would be fully compatible with mod_php. This doesn't work only because of the file permissions? So perhaps a second set-gui-permissions.sh would be a good nice-to-have feature.

RE: fastcgi incomplete headers issues - ephigenie - 11-11-2007 10:26 PM

Pls try changing your /etc/apache2/mods-available/fastcgi.conf
(or fastcgi_ispcp.conf accordingly)

Find the line with :
FastCgiConfig ...

and comment it out.
the place a new line beyound that with :
Code:
FastCgiConfig -idle-timeout 300 -killInterval 60 -multiThreshold 80 -startDelay 5 -maxClassProcesses 10 -maxProcesses 400 -minProcesses 10 -listen-queue-depth 400 -pass-header HTTP_AUTHORIZATION
maybe this helps.
This are the settings i'm currently using on this server we've had 500's for a long time.
And in addition since the isp-control.net domain is under heavy usage, i set
Code:
PHP_FCGI_CHILDREN=15
in my php-fcgi-starter.

Hope that helps.

Disabling fastcgi completely is not an option i would really consider seriously.
Because then there's only little protection left to keep intruders away from accessing data they do not own ...

RE: fastcgi incomplete headers issues - robmorin - 11-12-2007 11:58 PM

OK, i added those options to the config and restarted... i will keep an eye on the websites and log files to make sure i do not see any more..
incomplete headers in there!

Thanks for your help!
