Fixed In Version: httpd-2.2.15-53.el6
Doc Type: Bug Fix
Doc Text:
Due to a race condition in the termination of httpd child processes during a graceful restart, a child process could exit earlier than the main httpd process expected. Consequently, the main httpd process could try to communicate with an already exited child process, which could lead to a long delay when gracefully restarting httpd. With this update, httpd has been fixed to handle the described situation correctly, it no longer tries to communicate with exited child processes, and a graceful restart is no longer delayed.
