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

SUMMARY

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 can be caused by “overloading” the license server, even when a small number of licenses are currently activated.  This tech note will explain how to regenerate the license server trusted storage files to resolve the issue.

APPLIES TO

• AVEVA Enterprise License Server

SOLUTION

Delete trusted storage and regenerate the files. Complete the following steps:

1. Stop the License Server Core Service.
2. In File Explorer go to the folder C:\ProgramData\FNEServer.Delete the 3 files in that folder.
3. Start the License Server Core Service, which will create 3 new files in the FNEServer folder.
4. In the License Manager press Sync so that it is synched with FNO.
