Sorry for the late reply. But it might help someone having similar issue.
There was a firewall between two systems (distinct from CentOS iptables), which dropped (idle) connections after some time. Not sure about exact firewall config here. The Apache web server would throw an 500/503 error when it tried to reuse an open connection which firewall had already closed. The issue was resolved by using disablereuse parameter in ProxyPass directive. http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypass Thanks for the suggestions. -- Shantanu Pavgi.
