If there are an extreme number of files stored on a beacon awaiting upload then the Flexera Beacon Engine Windows service may fail with an System.OutOfMemoryException error appearing in the BeaconEngine.log file.


This issue may occur if there is an extremely large number (at least 100s of thousands) of files awaiting upload under the C:\ProgramData\Flexera Software\Incoming directory.

An error message like the following will appear in the C:\ProgramData\Flexera Software\Compliance\Logging\BeaconEngine\BeaconEngine.log file when this issue occurs:

2021-09-07 02:03:57,767 [es.BeaconStatusService|Engine] [ERROR] Failed to flush beacon status file to 'C:\ProgramData\Flexera Software\Incoming\BeaconStatus\20210906144513-{D001B164-48FD-3600-A397-7EA9EF82545F}.bstat'
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

   at Flexera.Beacon.Common.Services.BeaconStatusService.GenerateUploaderStatistics()

To mitigate this issue, arrange of the backlogged files to uploaded to the beacons parent, and then re-start the Flexera Beacon Engine service.

Alternatively, arrange to delete aged files which may not be necessary.
