I am using zenon 7.6 Energy edition here at a critical site and there seems to be an issue with the CEL. there was a disruption in the power supply of the server which caused the whole system to shutdown. When the system was restarted, we noticed that the events for 2 days were missing in the CEL. (The system shutdown on 5th at 10 PM, and was restarted on 6th 8AM, we have the events from 6th 8AM onwards and before 3rd 6PM but nothing in between 3rd 6PM and 5th 10PM).

Does anyone have any idea about what could be the issue here. and also is there a way to make sure the Event list is updated & auto-saved in hard disk at regular intervals, like every 15 or 30 min, etc.
