I've noticed this also starting with Apache2.2.
I see a large number of those internal dummy connection requests during 
an apache graceful restart (SIGUSR1) and at the same time the cpu load 
on the Apache2.2 server maxes out at nearly 100%.

I'm wondering if anyone else sees this high cpu usage with a graceful 
restart of Apache2.2.

My home page (GET /) is dynamically generated (although running under 
mod_perl) but I use the following mod_rewrite rule to make / a very 
uncostly http request when the HTTP_USER_AGENT is "internal dummy request".

RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} ^.*internal\ dummy\ connection.*$ [NC]
RewriteRule ^/$ /small_static_page.html [L]

Can anyone comment or confirm a similar experience with high cpu usage 
during a graceful restart of Apache2.2?

My OS is Linux 2.6.16-1.2133_FC5smp
