Summary0001186: Captive portal redir.cgi sometimes dies with a 500 Internal Server Error
Description
The Captive portal sometimes dies with a "Internal Server Error" code 500, which is shown to the user.

This error is caused by a failure to load/require the perl module "pf/web.pm" by the script "cgi-bin/redir.cgi". This can be seen via the apache error_log:

[Wed Feb 16 16:56:36 2011] [error] Attempt to reload pf/web.pm aborted.\nCompilation failed in require at /usr/local/pf/cgi-bin/redir.cgi line 24.\nBEGIN failed--compilation aborted at /usr/local/pf/cgi-bin/redir.cgi line 24.\n

This error, unfortunately, happens almost randomly, thus is difficult to reproduce consistently. I have experienced this error 5 times over 3 days, while playing with PacketFence.

Additional Information# apache2 -v
Server version: Apache/2.2.11 (Ubuntu)
Server built: Aug 16 2010 17:44:11

 Googling around for answers I now have a hypothesis/guess what wrong...

The following link explains that this situation can happen if another module modifies a value stored in the package space.

 http://goo.gl/rJmPl [^] (the real link gets screwed by mantis)

Looking through the comments in the code, the module pf::web::custom states that it "redefining subs in pf::web". Guess this could be the issue?

 Does this happens during you making changes to pf::web?

I know I restart apache each time I do some changes to pf::web otherwise I run into issues. mod_perl seems to be aggressive about code re-use and this 'caching' is per thread so a page refresh might work but another not.

Otherwise I'm not so sure, I mean we are in production on a lot of sites and I've never heard of such a high-rate of 500's (and we monitor logs).

 I have not used PacketFence for a while (been too busy on my other project www.iptv-analyzer.org).

But we actually have kickoff on the project, tomorrow, that need some of the functionality available in PacketFence. So, I'll soon be back on evaluation PacketFence ;-)
(Although, we have not decided if we are going to use PacketFence or not, in our setup)
