Subscriptions from streams to AI Bridge Processing Server lost after VMS reboot

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:

  1. Is this expected behavior in XProtect with AI Bridge?
  2. Should per-stream “processing settings” (subscriptions) persist in the configuration database after a reboot?
  3. Is there a way from Management Client to make these stream-to-app subscriptions persistent, or must they always be re-established programmatically?
  4. 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.

Hi @ofer apitz​ ,

Sorry for this late response. This is definitely not an expected behaviour.

Can you let us know which version of:

  • AI Bridge
  • Processing Server Admin plugin

Are you using ?

I will come back on it, thanks

Please let me know, what i can do asap, thank you.

Can you check the logs on the Management Client ?

Application.log + MIPtrace.log

We are using the MIP SDK to persist this information. We haven’t seen any issue in our installations :frowning: . But maybe there’s an exception being logged that we could use to ask the MIP team about it.

OK, I will get back on this.
