Package: libapache2-mod-fastcgi
Version: 2.4.6-1
Severity: normal
Tags: upstream patch

The exact error message I had in error_log is as follow : 

[Thu Jan 12 07:36:56 2012] [error] [client] (2)No such file or 
directory: FastCGI: failed to connect to server 
"/var/alternc/cgi-bin/php52.fcgi": socket file descriptor (1345) is larger than 
FD_SETSIZE (1024), you probably need to rebuild Apache with a larger FD_SETSIZE

This bug has already been reported for apache1.3 long ago : #280206 but was 
never fixed.

It is still buggy in apache2, but only appears when you have more than 1024 
file descriptors opened in Apache itself (in my case, more than 512 Vhosts with 
2 filehandle per vhost...)

The FD_SETSIZE check from fastcgi source code definitely looks like a buggy 
It checks that a file descriptor number is <1024, and pretends it may be above 
ulimit limits if that's the case... but that's useless: if you try to open a 
file above ulimit limits, you will have 0 as file descriptor returned from 
open() syscall...
More than that, it compares that file descriptor number with FD_SETSIZE, which 
is definitely not the maximum number of file an apache2 can open, you may have 
made it far higher with ulimit -n in the system configuration ...
So the patch I'm using since (successfully) is just removing that useless check 

Hope this can help solving this, don't hesitate to ask for help on this 
package, as you can see, I use it on many vhosts ;)
