3791805 - Unexpected system-wide stop of cluster protected ASCS/ERS after running sapcontrol on dialog instance to stop only one application instance

• While performing a change activity and trying to stop only one application server, the whole system went down unexpectedly.
• ASCS and ERS stopped although no maintenance was planned for these instances.
• history.glf shows: Stop instance by user "trusted unix domain socket user" from "localhost".
• sapstartsrv.log (or sapstartsrv.old) shows: "CN=..., O=SAP System PKI, C=DE is stopping SAP System at ".
• Cluster logs show sap_suse_cluster_connector executing stop (for example: fire_resource_action stop ...).
• The cluster set the resource meta attribute target-role=Stopped, preventing automatic restart until manually cleared.

• SAP ABAP/JAVA instance on Linux with HA cluster implemented
