What does your ProxyPass/ProxyPassMatch look like?
AFAICT connection_cleanup() closes the connection by clearing its pool
only if !worker->s->is_address_reusable ([1]), meaning disablereuse=on
or enablereuse=off was set ([2]), or the ProxyPassMatch contains a
$-substitution in the hostname[:port] part of the URL ([3]).

But it seems that mod_proxy_cluster is creating and initializing its
own proxy workers, and I don't know which games it plays on its own
with worker->s->disablereuse or worker->s->is_address_reusable or
worker->s->is_address_reusable.
