Bug 1775714

rhsmd is not specifically for informing rhsm-icon, but also other items within the subscription-manager chain. That is to say that this informs multiple (or available) pieces about changes in entitlement status (including via DBus API) to trigger notifications or actions.

That makes restating that this bug is that after running `subscription-manager status`, rhsmd is triggered and never ends (hangs).
This could be environmental based on networking, or there could be an issue with rhsmd's execution in this scenario (likely).

*** Bug 1775713 has been marked as a duplicate of this bug. ***

The impact is actaully severe. When rhsmd doesn't exits, it continues to talk to satellite server and drive up load. In large enviroment we can see degradation of performance over time.

I can reproduce the the bug report for several cases.

1. case

When a system is not registered and I run status command, then I'm able to reproduce the bug report:

[root@fedora30 candlepin]# ps aux | grep rhsmd
root     22311  0.0  0.0 215744   900 pts/1    S+   16:22   0:00 grep --color=auto rhsmd

[root@fedora30 candlepin]# subscription-manager status
+-------------------------------------------+
   System Status Details
+-------------------------------------------+
Overall Status: Unknown

System Purpose Status: Unknown

[root@fedora30 candlepin]# ps aux | grep rhsmd
root     22314 11.0  2.6 306412 54512 ?        Ss   16:22   0:00 /usr/bin/python3 /usr/libexec/rhsmd
root     22316  0.0  0.0 215744   896 pts/1    S+   16:22   0:00 grep --color=auto rhsmd

Interesting is that clean command stops rhsmd process

[root@fedora30 candlepin]# subscription-manager clean
All local data removed
[root@fedora30 candlepin]# ps aux | grep rhsmd
root     22331  0.0  0.0 215744   892 pts/1    S+   16:23   0:00 grep --color=auto rhsmd


2. case

When system is compliant, then I can reproduce starting of rhsmd too:

[root@fedora30 candlepin]# subscription-manager register --username admin --password admin --org admin
Registering to: svice:8443/candlepin
The system has been registered with ID: 66091455-7d18-4b0a-88e2-f2d8976b40b6

[root@fedora30 candlepin]# ps aux | grep rhsmd
root     22442  0.0  0.0 215744   832 pts/1    S+   16:24   0:00 grep --color=auto rhsmd
[root@fedora30 candlepin]# subscription-manager status

[root@fedora30 candlepin]# ps aux | grep rhsmd

root     22459  0.0  0.0 215744   896 pts/1    S+   16:24   0:00 grep --color=auto rhsmd


[root@fedora30 candlepin]# subscription-manager attach --auto

[root@fedora30 candlepin]# ps aux | grep rhsmd
root     22556  0.0  0.0 215744   832 pts/1    S+   16:25   0:00 grep --color=auto rhsmd


It is interesting that attaching required pools using --auto option stops rhsmd too.


3. case

When system is current and I run status command, then only unregistering can stops rhsmd process:

[root@fedora30 candlepin]# ps aux | grep rhsmd
root     22556  0.0  0.0 215744   832 pts/1    S+   16:25   0:00 grep --color=auto rhsmd


[root@fedora30 candlepin]# subscription-manager status
+-------------------------------------------+
   System Status Details
+-------------------------------------------+
Overall Status: Current

System Purpose Status: Mismatched
- The requested add-on "" is not provided by a currently consumed subscription.


[root@fedora30 candlepin]# ps aux | grep rhsmd
root     22634  8.2  2.7 306412 54960 ?        Ss   16:30   0:00 /usr/bin/python3 /usr/libexec/rhsmd
root     22647  0.0  0.0 215744   896 pts/1    S+   16:30   0:00 grep --color=auto rhsmd

It is necessary to mention that rhsm-icon (part of subscription-manager-gui) cannot be running to be able to reproduce cases in step #13.

rhsm-icon is automatically started using XDG (/etc/xdg/autostart/rhsm-icon.desktop), when user uses desktop environment (GNOME/KDE) and is logged-in.

Moving bug to verified as I dont see rhsmd process running status or attach or register command
