Apache won't proxy

[tsm]

I have 2 servers configured identically except for the hostname. They're both RHEL 6 VMs based off the same image.

For some reason one server will not proxy. After setting the error log to debug, I see that the bad server stops at:

[debug] proxy_util.c(1934): proxy: initialized single connection worker 0 in child 2781 for (localhost)

The good server continues on to canonicalize the proxy URL and route the request.

Any ideas what could be wrong? Do I need to scrap this VM and start over?

EDIT: Okay, weird, it works in the main httpd.conf file, but not in my virtual host configuration file.

Okay, figured it out myself. For some reason the /etc/hosts file was really messed up.
