Memory leakage ClearScada Database Server 2017

Hi all,

I wonder if you have experience of memory leakage in ClearScada Server 2017 and how to solve it?

Since I started to upgrade sites from ClearScada 2015 to 2017 I noticed that the memory use for ClearScada Database Server is growing very fast. After a couple of weeks, the memory is between 1500-2000MB and finally ClearScada stops working properly. It usually starts with frozen values for the analog signals and later on the ViewX crashes.  

I use advanced OPC Driver for the signals and connect to a KEPserverEx OPC. I have between 2000-5000 advanced OPC signals in ClearScada and I have tried to turn off all logging and historic but it doesn’t help.

The memory in ClearScada 2015 was always stabile at 80-110MB with simple OPC Driver.

Best regards

andgus

I don't see any specific known leaks in the advanced OPC driver. Please raise this with Support.
