Please note that we have multiple tomcat instances supported by one
common apache httpd server. I just added the one (Tomcat 7) which is
having this issue (server hung). All remaining tomcat's are running
on Tomcat 6 version.

Pradeep,
In general, it's not a good idea to reference a zip file. Post
information inline without comments, and with sensitive information
obscured (not removed - since that can alter the configuration meaning).
I'm posting the relevant portions of the configuration inline, since I
don't think it's fair for future readers to have to find zip files and
unzip them.

If I've left out salient portions of httpd.conf, I apologize. mod_proxy,
mod_proxy_httpd, mod_proxy_ftp, and mod_dav are all in use.
mod_proxy_ajp is not (since mod_ajp is).
I suggest that you read very carefully the following:
http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html
http://tomcat.apache.org/connectors-doc/reference/workers.html
http://tomcat.apache.org/tomcat-7.0-doc/config/ajp.html
Also, read the example workers.properties file found in the conf
directory of the source distribution for the Tomcat connectors.
In particular, start with the documentation concerning
connection_pool_timeout.
There are other settings here that are either not used (because you
haven't set the directive the settings alter), or don't exist.
In httpd.conf, you have:
ServerLimit 1536
MaxClients 1536
This seems to be a bit excessive.
There is a lot more, however this should give you enough to get started.
. . . . just my two cents
