CF 10 with Apache on Centos 5.8

Question

Hi,Cannot get my install to render the CF Admin pages succesfully, keep getting a 503 - Service temporarily unavailable.Log files all look clean with the exception of the Tomcat log file which gives a load of the below:[Mon May 21 21:54:30 2012] [3457:47024938890000] [info] init_jk::mod_jk.c (3299): mod_jk/1.2.32 () initialized[Mon May 21 21:54:30 2012] [3458:47024938890000] [info] init_jk::mod_jk.c (3299): mod_jk/1.2.32 () initialized[Mon May 21 22:02:54 2012] [3461:47024938890000] [error] jk_open_socket::jk_connect.c (448): socket() failed (errno=22)[Mon May 21 22:02:54 2012] [3461:47024938890000] [info] ajp_connect_to_endpoint::jk_ajp_common.c (1027): Failed opening socket to (127.0.0.1:8012) (errno=22)[Mon May 21 22:02:54 2012] [3461:47024938890000] [error] ajp_send_request::jk_ajp_common.c (1649): (cfusion) connecting to backend failed.

This is by design, as part of various CF10 security enhancements.

For instance, in this article on CF10 Security enhancements (http://www.adobe.com/devnet/coldfusion/articles/security-improvements.html), it notes this with respect to changes about CFLOGIN, which the CF Admin uses under the covers:

Now you can have only one active session open for one user for a given application that uses the cflogin tag.

For example, you can now access the Administrator console one user at a time with a given set of UserIDs and passwords.

It’s also in the CF10 docs, though not worded as obviously applying to this situation. At the bottom of http://help.adobe.com/en_US/ColdFusion/10.0/Developing/WSe61e35da8d3185183e145c0d1353e31f559-7ff7.html, it says:

You are logged out from one of the ColdFusion administrators, if:

From the same host, you log in to the ColdFusion (10) Administrator and the ColdFusion Administrator of an older version.

HTH.

I should have added that while you may think, "but that doesn't explain why another user and I can't use it at once", actually it does. Note that the login is not "per user" but "per account". And by default, there is one account used for logging into the CF Admin, called the Admin user (we normally don't even notice or use that, and only need to enter the password for that account).

So it's saying that "2 users of the same account can't be logged into the CF Admin at one time." I agree it's an annoyance, but I'm sure there's a worthy security problem for which it was the solution. Maybe someone from Adobe will chime in with more thoughts.
