Hello.

I am glad it works, although I do not quite understand your post.
Out of curiosity, does it mean that the memory consumption was not on the client side (as I have assumed), but on the server side?

Also, I think you have misunderstood what I was asking for. Even if you do not get an error inside the program, there surely *was* something like an error message and other observable symptoms - otherwise you wouldn't be able to tell that " the memory gets full and my application crashes". So, I was asking for the information that lead you to reporting it.

Best regards

Thank you so much for your message. I get no error code or exception!
I found the problem! The problem was in the 'writeValue' function where I searched for the OPC UA Variables in the OPC Server. Probably it is a big burden on OPC Server's shoulder! I transferred the search process to the OPC Client side in Delphi (in a dynamic array) and my application is running.

Hello,

can you please provide the full&precise error message that you get, regarding the memory condition?

Thank you

Hello.

We will try to reproduce it, and will let you know then here.

Best regards

Dear all,

I have an OPC UA Client application in Delphi 10.2. Via my application I connect to the OPC Server and try to write variables continuously into the OPC Server. I can successfully connect to the server and write the variables, but after a couple of seconds the memory gets full and my application crashes. In the attachment you may find a copy of my code. In the function 'WriteItem' I call another function 'WriteItemValue(Name,ItemValue)' and try to write into the OPC Server. I tried to give OPCUAClient object free in different positions, but it doesn't work! I would be really happy if someone can help me.

Regards,
Moien
