[users@httpd] Mod_Proxy Bug in Apache 2.0.65

[Otis Dewitt - NOAA Affiliate <ot...@noaa.gov>]

Greetings,

I am using Apache 2.0.65 with mod_proxy as a reverse proxy, this proxy sits
in the DMZ and serves to the backend servers. I am getting constant errors
in the log file stating whats below.

*[Tue Dec 10 12:33:17 2013] [error] (20014)Error string not specified yet:
proxy: pass request body failed to 192.168.2.5:7710
<http://192.168.2.5:7710> (example.com <http://example.com>) from
192.168.2.5:7710 <http://192.168.2.5:7710> ()*

I have searched many forums to only find people with the same issue that
has not been answered. This error message is very vague and points to no
where to start looking. The URL works but occasionally gets "Internal
Server Error" due to this issue.

I have managed to find this out by using the 192.168.2.5:7710 directly
without the proxy and it works flawless, below you can find my proxy
directives.

 #Prevent the use of this httpd server to be used as a proxy
    ProxyRequests Off
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyHTMLMeta On
    ProxyPreserveHost On
    ProxyVia on

    ProxyPass /jira https://example.com:7710/jira
    ProxyPassReverse /jira https://example.com:7710/jira


1. I would like to know what is causing this problem?
2. How can I solve this problem?

Thanks,
Otis
