Hello,
We are working with AI Bridge and custom IVA applications. After a Milestone Management Server reboot, all services recover correctly:
- AI Bridge restarts normally.
- IVA applications re-register successfully.
- Metadata topics themselves are still present in the system.
However, the subscription from each video stream to the processing server (the binding of a stream → app → metadata topic) is lost. In other words, the topics exist, but the per-stream subscriptions to the app do not survive a reboot. We need to go back into Management Client and re-apply the processing settings each time.
Questions:
- Is this expected behavior in XProtect with AI Bridge?
- Should per-stream “processing settings” (subscriptions) persist in the configuration database after a reboot?
- Is there a way from Management Client to make these stream-to-app subscriptions persistent, or must they always be re-established programmatically?
- If persistence is supported, can you point us to the correct configuration or workflow to ensure subscriptions survive restarts?
Any guidance on whether this is a configuration issue or a product limitation would be very helpful.
Thank you.
