Adding bugfix adv for 3 apache mga#10591
1 claire 182 type: bugfix
2     subject: Updated apache packages cure a timeout when stopping or restarting the service
3     src:

5     core:
6     - apache-2.4.4-7.1.mga3
7     description: |
8     A problem was found with the httpd systemd unit files that frequently
9     resulted in a deadlock when stopping or restarting the service.
10    
11     The unit file was configured to use the httpd -k graceful-stop command
12     to stop the running instances of httpd. This command is asynchronous but
13     systemd expects the command to be synchronous, only exiting once all the
14     processes have stopped. This causes systemd to send a SIGTERM to all
15     processes remaining in the cgroup which can cause problems for the
16     shutdown process resulting in the deadlock. systemd would later send a
17     SIGKILL which would properly kill the processes but this would only happen
18     after a timeout.
19    
20     This update changes the systemd unit to not send the initial SIGTERM and
21     thus waits for the processes to exit normally before (if things don't go
22     well) calling SIGKILL as before after a timeout.
