Subject DO NOT REPLY [Bug 48363] New: Intermittent error "Address already in use: proxy: HTTP: "
Date Thu, 10 Dec 2009 10:24:17 GMT

           Summary: Intermittent error "Address already in use: proxy:
                    HTTP: "
           Product: Apache httpd-2
           Version: 2.2.9
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_proxy_http

Since upgrading a number of boxes from 2.2.6 to 2.2.9, I'm seeing occasional
errors like this:

:[Wed Dec 09 16:05:16 2009] [error] (125)Address already in use: proxy: HTTP:
attempt to connect to (*) failed

resulting in an HTTP 503 being sent back to the client. I'm using
mod_proxy_http and mod_rewrite; for example

RewriteCond %{REQUEST_URI} ^/files/(.*)
RewriteRule (.*) http://localhost:8080/app/url?param=%{ENV:SCRIPT_URI} [QSA,P]

I get on average 5-10 failures per day on a system which processes ~500000
proxy requests/day, fewer on quieter systems. A much busier system with 2.2.6
does not show the problem. 
The errors appear at apparently random intervals, they don't generally cluster,
and don't appear to coincide with particularly high load on the system. Other
requests are successfully served at the same time as the errors are returned.

As far as I can tell there is no issue with the back-end server (a JBoss app
server in this case).

I haven't, unfortunately, been able to update a sufficiently busy system to a
version later than 2.2.9 to determine whether that fixes the problem
