Description Derek Poon 2012-11-29 00:31:10 UTC
Error message says...

AH00554: Access to file /etc/apache2/conf.d/ denied by server: not a regular file
apache2: Syntax error on line 227 of /etc/apache2/apache2.conf: Could not open configuration file /etc/apache2/conf.d/: Bad file descriptor


To reproduce...

The server root is /etc/apache2.
The configuration file /etc/apache2/apache2.conf contains:
  Include conf.d/
Run `httpd -t -f /etc/apache2/apache2.conf`


This is a bug because...
It used to work in Apache 2.2, but fails in Apache 2.4.3.  Nothing in the release notes suggests that it was intentionally changed, so it's a regression.


Suggested workaround...
Include conf.d/*
