Httpd (apache) won't stop gracefully when user is logged in the gui

Distro Discussion & Help
1

I noticed a delay in shutdown and reboot with FreePBX distro in certain circumstances. After investigating I discovered that the problem is with httpd (apache). It won’t stop gracefully when I’m logged in the GUI.

FreePBX version:

$ cat /etc/schmooze/pbx-version
12.7.6-1904-1.sng7

This is a testing environment in VM (Virtualbox and proxmox KVM). I have made tests with clean install (not even updated the system), with updates applied, with my configs applied (ansible), with a restore from the system in production. In all the cases the result is the same.

Steps to reproduce:

  1. Login in the FreePBX GUI and stay logged in.

  2. In the terminal (CLI) stop httpd (apache)

    $ systemctl stop httpd

The command will take ~90 seconds to terminate.

This is the output of journalctl -f -u httpd.service during those 90 seconds:

Oct 21 08:57:08 freepbx.sangoma.local systemd[1]: Stopping The Apache HTTP Server...
Oct 21 08:58:38 freepbx.sangoma.local systemd[1]: httpd.service stop-sigterm timed out. Killing.
Oct 21 08:58:38 freepbx.sangoma.local systemd[1]: httpd.service: main process exited, code=killed, status=9/KILL
Oct 21 08:58:38 freepbx.sangoma.local systemd[1]: Stopped The Apache HTTP Server.
Oct 21 08:58:38 freepbx.sangoma.local systemd[1]: Unit httpd.service entered failed state.
Oct 21 08:58:38 freepbx.sangoma.local systemd[1]: httpd.service failed.

If I start the service again and logout from the GUI, then the service takes ~2 seconds to stop, which I assume should be the normal behaviour.

I found nothing useful form apache logs. Not even with debug turned on. I can show you the logs if you want.

This is causing the VM to take ~1.5 minutes to shutdown, which is a problem for me.

Is this normal? One has to be logged out the GUI for the system to shutdown clean?

In passive testing I can confirm this.

With the UI closed
apachectl stop
is almost instant.
with the UI open, it is not.

running
apachectl status
during the delay shows

   CGroup: /system.slice/httpd.service
           |-25833 /usr/sbin/httpd -DFOREGROUND

That may provide someone the needed data to fix the issue(s).

Doing more tests I found out the delay only occurs when the user is in Dashboard (apparently).

If I go to “Reports > Asterisk Info”, for example, and then stop asterisk, it stops normal, without delay.

So, the problem seems with the Dashboard module.
