[error] (OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : proxy: HTTP: attempt to connect to 1.2.3.4:80 (1.2.3.4) failed
... hundreds of megabytes of these errors.
10048 is WSAEADDRINUSE. It seems to happen in proxy_util.c in
ap_proxy_connect_to_backend() when apr_connect() is called.
My interpretation is that the host is out of free local ports. 'netstat' also shows a very large number of connections.
Is my interpretation correct? Is there anything that can be done? Has anyone else seen this?
your interpretation sounds correct to me
