[Mongrel] high cpu load

Ok, let me clarify the terms I have used and add more information to the

Very low usage = no user accessing it. Plus, my application doesn't have any
"background" operations. Thus, the log is empty. The rails version is 1.2.5
and ruby is 1.8.6.

Other than that, my server is running on a linux box, this is the uname -a
command for it:

Linux localhost 2.6.9-42.0.3.ELsmp #1 SMP Mon Sep 25 17:28:02 EDT 2006 i686
i686 i386 GNU/Linux

Moreover, I am running a mongrel cluster (1.0.2) with 1 (one) instance, so
it is almost the same as running mongrel alone. This instance is not
proxied, balanced or accessed thru any other software (apache, for example).
My server configuration is pretty standard, the only plugins I have are
redcloth and WhiteListHelper. 

My app database is Mysql (4.1), where I use an UTF-8 database.

I hope this is enough info to start a discussion.

Thanks and regards,

How is it possible for us to offer any insight at all without knowing
your application, your server config, database, your logs, your
hardware etc...

people are pretty darn helpful on this list but by no means that means
they are psychics.

try to be as verbose as possible when posting questions to any list if
you expect to get help.
