Apache broken, problems with suEXEC?

[be-hosted]

Hello,

this afternoon I got a call of one of my customers stating that he received a lot off errorcode 500 when visiting his site.
When I checked this I've got it also, 2-3 times I got this error msg telling me that the server was overloaded (load was 2.3 and 143 proc's running).

So I decided to stop and restart apache, but I got when restarting apache this error msg
magneto init.d # ./apache2: line 73: 350 Aborted ${APACHE2} ${APACHE2_OPTS} -k start [ !! ]



magneto init.d # apache2
Syntax error on line 26 of /etc/apache2/vhosts.d/medusa.conf:
Invalid command 'suPHP_UserGroup', perhaps mis-spelled or defined by a module not included in the server configuration

in the error_log of apache I find this :
[Fri Feb 02 16:16:49 2007] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec2)
apache2: stack smashing attack in function RAND_poll()


So i have no idea how I can get apache working again (about 250 sites down)

can someone give me some help with this.
I already rebooted the system, but no go.

thx!

Maybe some more info would help :
magneto init.d # equery depends net-www/apache
[ Searching for packages depending on net-www/apache... ]
dev-util/subversion-1.1.1-r3
net-mail/mailman-2.1.5-r4
dev-php/suphp-0.5.2
www-apache/mod_evasive-1.10.1
net-www/mod_fastcgi-2.4.2
net-www/mod_bw-0.6

magneto init.d # emerge --pretend --verbose --update --newuse --deep subversion mailman suphp mod_evasive mod_fastcgi mod_bw

These are the packages that would be merged, in order:

Calculating dependencies -
emerge: there are no ebuilds to satisfy "dev-php/php-cgi".
(dependency required by "dev-php/suphp-0.6.0" [ebuild])

Can please someone help me on this one?
I have no clue what is going wrong and I have loads of customers calling me like crazy.

The server is a dual opteron with 2gb mem and raid5 scsi disks

Ok, got some things solved.
First of all I'm able to restart apache, seemed he was hitting the open file limit (more than 1024 hosts (domains + subdomains) in his conf.
So I deleted a 80 vhosts (that didn't exist annymore).

But now I can't get php working, html and so on is no problem, but when I want go to a php website or php script I get a downloadbox and get the php file without any parsing, so I stopped apache, otherwise some db logins and so on are hitting the streets, and that's not the point.

I update suphp to 0.6 (latest version I think) but no luck.

Someone any idea how to resolve this issue?
Out of ideas at the moment on this one
