LinuxQuestions.org - Internal dummy connection

Hi all,

congratulations by this great forum. There are a lot of available info.

I have a problem of performance in Linux Server. I don't know why but this linux server have a seriously problem of stability. Then i was reviewing httpd logs when i found a lot of this kind of entries:

Code:

::1 - - [21/Oct/2007:12:31:18 +0100] "GET / HTTP/1.0" 403 3931 "-" "Apache/2.2.2 (Fedora) (internal dummy connection)"

I found in some webs information about optimal setup to avoid this. These webs explain the normal setup to a normal-busy server.

Code:

StartServers    16

MinSpareServers  8

MaxSpareServers   64

MaxClients       256

MaxRequestsPerChild  4000

And these ones are the actually setup of MPM-prefork

Code:

<IfModule prefork.c>

StartServers      8

MinSpareServers    50

MaxSpareServers  20

ServerLimit      1024

MaxClients      1024

MaxRequestsPerChild  4000

</IfModule>

Here i found the work and prefork concept. I don't know what these mean. The only i sure know is that my apache is in prefork mode(httpd -V). So i understand that the interesting files to my httpd.conf setup are those start after

Code:

##Server-Pool Size Regulation (MPM specific)

##

# prefork MPM

Its very strange because this server don't have a large amount of traffic. Only have a some WordPress blogs, one or two SMF forums and little more. So is for my a great problem because i can't explain the inestability of system.

I will continue finding information about this issue. Any help will be very helpul. Thanks :)

PD: output of httpd -V
