I am concerned with my NServiceBus solution.

I have a “MessageHub” that publishes some very important messages. But sometimes it loses track of its subscriptions and just discards the message because it thinks no one is listening.

I have tried turning on “NServiceBus.Integration” to store the subscriptions. But despite that, I still have issues with bad start up order where it thinks nothing is listening.

Is there a way to debug this process? Try to figure out why it is getting confused?

I don’t even know a way to look at what subscriptions it “thinks” it has…

I went with NServiceBus because it is not supposed to lose data ever. Now I am losing large chucks. I know it is a config issue, but it is causing much grief.

    What is probably happening in your case is that you are using MSMQ for subscription storage. Even though it’s possible for subscriptions to endure for a while, using MSMQ to store things long term is always going to be volatile.

    For durable subscriptions storage (which survive “forever”) you should be using SQL server as your subscription storage.

    Note: You can always view your current subscriptions whether you are using sql or msmq to store them. In SQL just look in the subscriptions table and for msmq look in the publisher’s subscription queue.

    UPDATE

    Since version 3 I have been using RavenDb which is the default.
