License Server Core Service goes into a STOPPING state and machine must be rebooted in order to recover

The AVEVA Enterprise License Server repeatedly goes into a "Stopping" state.  When this happens, a reboot is required to restore it to Running.  The following message appears in the OCMC logs:

LS Agent can't use the ServiceController API to control the LS. Time out has expired and the operation has not been completed. Stack Trace: at System.ServiceProcess.ServiceController.WaitForStatus(ServiceControllerStatus desiredStatus, TimeSpan timeout) at LicServer.WindowsService.TrackSELicServer.MonitorLicServer()

This tech note will explain how to regenerate the license server trusted storage files to resolve the issue.

Cross-node encrypted SuiteLink requires both nodes to be joined to the same System Management Server (SMS) server.

Migration of Galaxy to System Platform 2023 Never Completes

When migrating a Galaxy from an older version to System Platform 2023, the process hangs without any errors or warning and never completes.

By default, the migration process handles 500 templates at the same time from the original Galaxy. If there are more than 500 templates, this may exceed the 3.5 GB that aaGR process can handle, causing a crash as we see in the Log Viewer.

This tech note provides the steps to change the default MaxTemplateCacheSize from 500 templates to 10 to make sure the 3.5 GB limit is not violated.

Popup Window Does not Appear when Clicking “Select” in Tagname Dictionary

When working in the Tagname Dictionary in an InTouch HMI application, clicking the Select button should cause the Tag Browser popup window to appear, allowing the user to browse the existing tags in the application.

Under certain conditions, the popup window will not appear after clicking Select and the WindowMaker application will freeze up, forcing the user to shut down the application.

This issue is caused when WindowMaker attempts to open the Tag Browser on a second monitor when no second monitor is present.  This tech note will provide the steps to resolve the issue.
