No, I am not aware of any reason (technical or license-wise) why 50 servers should represent some limit.

Thanks for the quick reply on this issue and the other issue I am having.

OK, I set .Isolated = true, which seems to have solve the issues in the quick testing I've done. I need to so more thorough testing but so far so good.
EasyUAClient easyUaClient = new EasyUAClient {Isolated = true};
One quick question. Is there any reason why I would be having issues connecting to more than 50 devices? Last night while testing I tried to add devices 51, 52 & 53. The failed to connect to these devices. I've connected to the devices before so I don't this it is a hardware issue. Since this issue happened at the even number of 50, I just wanted to ask the question before digger deeper into the issue. Are there any licensing issues?

This is by design (it would be a lengthy explanation).
If you are truly using one EasyUAClient with each server, setting .Isolated = true on each instance after its creation should resolve it, I think.

Best regards

EasyUAClient.ServerConditionChanged firing multiple time per event was created by sjscheider
In our application, we are subscribing to 3 nodes on many servers/devices. For each device/server, we create a new EasyUAClient object and subscript to the ServerConditionChanged event for each EasyUAClient object. When a ServerConditionChanged event fires for a single device, we receive multiple events, one for each device/server we are connected to. So as our app starts and we attempt to connect to 5 devices, we'll receive one "Connected" event when for device 1 and 5 "Connected" events for device 5.

Here is the code we are using to subscribe to the event, seems pretty straight forward.
easyUaClient.ServerConditionChanged += ServerConditionChanged;
Is this done by design? Am I doing something wrong in my code? Is this a bug?
