Sorry for the late reply.

I am using OpcLabs.EasyOpcUA version 5.63.246.1, I have a reproducible scenario.

I am writing to the PLC about 150 tags every 3 seconds and the system grows in memory usage and when it reaches 1.5GB the system explodes.

Regards.

Hello,
as you can see from the forum thread below, the customer did not answer our question, and consequently we have not followed up.

Which QuickOPC version are you using? Do you have reproducible scenario?

Best regards

Sorry for reviving such an old topic, but did you find a solution to this problem? The same thing is happening to me recently. Each call to WriteMultipleValues increases the memory and after a while my application throws System.OutOfMemoryException.

My application is in C# .Net Framework.

Hi,
I get the problem that each execution of WriteMultipleValues, the memory grow about 200kB.
This not happend with single WriteValue.
Is there some freememory function?

Thanks,
Krzysztof
