OPC UA C# client subscription issue

[mrahman252003]

I inherited some C# opc ua client code. I see we loose subscription time to time.

m_Subscription = new Subscription(session);
m_Subscription.PublishingEnabled = true;
m_Subscription.PublishingInterval = publishingInterval;
m_Subscription.DataChanged += SubscriptionOnDataChanged;
m_Subscription.NewEvents += SubscriptionOnNewEvents;
m_Subscription.StatusChanged += SubscriptionOnStatusChanged;

m_Subscription.Lifetime = 10000;
m_Subscription.MaxKeepAliveTime = 10000;
m_Subscription.Create();

With the above code, I lost subscription time to time meaning SubscriptionOnDataChanged is not called. I am not explicitly calling to stop publish. To get the working subscription back what I should do?

What does it mean for C# client? Can any body show or explain me?

Hello,

Is SubscriptionOnStatusChanged EventHandler called? Is the connection established the whole time, or is the client in a reconnect loop?
