Any idea on what causes this? These alarms are popping up non-stop and quite annoying. Just trying to clean up the alarm console.
so this is an alarm raised on a secondary hub, correct? (the list_subscriber is a callback from the hub probe).
Can you check if there are any free subscribers on the primary hub? If this is a Windows based hub there is a hard-limit of 64 subscribers imposed by the OS that could causes issues.
If you run the call back directly via the probe utility against the primary hub probe, it should tell you many subscribers are currently being handled.
