Fixed In Version: httpd-2.4.6-34.el7 Doc Type: Bug Fix
Doc Text:
The httpd daemon did not reset an internal array for storing variables defined using the "Define" directive. Consequently, variables could be undefined after a graceful restart. httpd has been fixed to reset this internal array during a graceful restart, and variables are now correctly defined in this scenario.

Example configuration that will lead to a crash on graceful reload

Description of problem:

Defined variables in Apache HTTP server version 2.4.x in RHEL 7 are not properly handled during graceful restarts, leading to variables suddenly becoming undefined or other unpredictable behaviour.

Version-Release number of selected component (if applicable):

Reproduced with httpd-2.4.6-31.el7.x86_64

How reproducible:

Every time.

Steps to Reproduce:
1. Define a certain set of variables (Example configuration attached)
2. Make the variable a part of a configuration item
3. Reload Apache

Actual results:

The variables apparently get undefined and any configuration using the value of the variable will result in a syntax error.

Expected results:

No errors.

Additional info:

The problem is discussed at https://bz.apache.org/bugzilla/show_bug.cgi?id=57328, and was fixed in 2.4.10.
