Dear all,
We currently have the following SCADA setup:
-
AVEVA Plant SCADA 2023 R2 (June 2025 patch)
-
Distributed system: 1 Primary Server, 1 Backup Server, 1 Dev workstation, 2 Viewers
-
All servers are Windows VMs on a Proxmox cluster
-
Licensing: AVEVA Enterprise Licensing (AEL / Enterprise License Manager), software-based license, valid and not expiring
Since installation one year ago, SCADA services crash with Software Protection Failure and automatically restart approximately every 2 hours.
Based on the sample syslog below, it looks like it tries to check for USB Dongle License, while we are using Enterprise License Manager.
Anyone has suggestions on how to prevent such behavior?
Thank you very much in advance for your help and guidance.
