In a high-availability deployment of Business Central, deploying a service to a KIE Server using Business Central intermittently fails [RHPAM-2830]

Issue: In a high-availability deployment of Business Central, Sometimes the service is not deployed to a KIE Server when you use the Business Central user interface in a high-availability deployment.

For instructions about enabling this setting, see Enabling the OpenShiftStartupStrategy setting to connect additional KIE Servers to Business Central in the Deploying a Red Hat Process Automation Manager authoring environment on Red Hat OpenShift Container Platform document. You must complete this procedure even if you do not connect any additional KIE Servers to Business Central.
