Hello.

I do not know what these messages represent. Their texts do not com from our software.
If they are generated by something in your code that is tied to QuickOPC, you need to explain under which conditions they are generated.

Best regards

We are using QuickOPC 5.22 within a VB.Net application built in Microsoft Studio 2010.

We are experiencing some intermittent faults with the system and a concern has been raised that it might be linked to 'Client detached from server' and
'Client attached to server' messages seen on the OPC log. Please find an example OPC log attached which shows these messages (e.g. @ 04.05.2020, 14:14:52).

Is this normal behaviour? Is it possible that events from subscribed items are being missed in between the 'detached' and the 'attached' messages?
