server surcharge

[Nassou]

Hi guys

i have a big big probleme with surcharge of my server and database error !


I think that a relationship with the hack: good now when I turn these hack is the catalyst:

Cyb - Statistics Advanced Forum
Latest X Threads Forum on Home
vBSEO
vBSEO:: Sitemap Generator

I looks on with TOP, so I watch httpd very frequent and mysqld

What is surprising is that the former host while niquel worked with these hack but this is the big overload what's more I really need this hack!

I present below my configuration:

httpd.conf

#
# This is the main Apache HTTP server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
