I don't think that your problem is the same problem as described by many others
here. It is also no surprise to me that force-proxy-request-1.0 and
proxy-nokeepalive show no effect in your situation as you are using mod_rewrite
to do reverse proxying to a single server (a balancer would be a different
story). In this case httpd NEVER reuses the backend connections. For each
request to the backend a new one will be opened.

Above (the star) proves that you are using the 'reverse worker' which never
reuses backend connections. 
So it looks like your fresh backend connections get broken for some other reasons.
