Mod_Proxy Bug in Apache 2.0.65 (Apache Users)

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 (example.com) from 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>

#Proxy related options

    ProxyHTMLMeta On
    ProxyPreserveHost On
    ProxyVia on

## Jira [PROD]
    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
