Firewall on the Tomcat server forbidding access to the port?
What if you try to:
- ping the host (unless the firewall blocks that too),
- telnet thehost 8009
?

I have checked 503 error comes in apache access logs while apache error logs
show below error.

Have you configured the tomcat engine with route=public1 ? I think you
should put something like jvmRoute="public1" in the server.xml file

Is the request actually reaching the Tomcat server? When using a proxy the
error from the end point server will also appear in Apache logs as if Apache
is misconfigured when in reality the 503 may be coming from Tomcat because
of a misconfiguration there.
Check both logs and see if the request is reaching Tomcat. It may point to
more details on the issue.
