将带有反向代理的Apache（2.4）SSL站点加载到Tomcat（6.0）时出现问题

Question

I've been running a site for the past 3 years with out any issues. The current SSL certificate was applied the past December. It is running on the FreeBSD 10 operating system. Apache is configured as a reverse proxy passing to Tomcat 6.0. As of this week the initial loading of pages has become extremely slow and does not leave any messages for the user. Nothing seems to stand out in my logs either. I will try to post the configuration below in hopes someone with a fresh set of eyes sees something I'm overlooking. There have been no modifications to the configuration since the site was stood up. If you need any additional info I'll be happy to provide.

Thanks

Turns out the issue was not with the Apache configuration nor tomcat at all. The web app was calling a REST API that was suddenly taken offline due to getting DDoS attack. We commented this call out and all works great. Thanks for those who looked at this and made suggestions.
