do you read
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypass there are
new options for ProxyPass 2.2.X
"Connection pool worker retry timeout in seconds. If the connection pool
worker to the backend server is in the error state, Apache will not
forward any requests to that server until the timeout expires. This
enables to shut down the backend server for maintenance, and bring it
back online later."

Hello Christian!

2.0.59 mod_proxy, but dont ever observed the problem that you described.
by every HTTP request you send to apache, apache tryes to reach the
backend, try to sniff the traffic between client -> reversproxy &
reverse proxy -> backend to see whats happening.
it may be an configuration failure
Do you have any hint, which one?
