Hi Dojo,

I occasionally bump into this kind of system notice where an exception is triggered,
with the following stack trace: any hint, please?
Thanks

(I've changed the actual server name into DMA01 before sharing this)

* Notice Alarm: 'DataMiner run-time' is 'Unexpected Exception [Exception from HRESULT: 0x8004028A]: The client is unknown.
(Element Subscription)

Server stack trace:
at Interop.SLDataMiner.IDataMiner.NotifyDataMiner(String bstrUser, Int32 iType, Object varValue, Object varValue2, Object& pvarReturnValue)
at System.Runtime.Remoting.Messaging.StackBuilderSink._PrivateProcessMessage(IntPtr md, Object[] args, Object server, Object[]& outArgs)
at System.Runtime.Remoting.Messaging.StackBuilderSink.SyncProcessMessage(IMessage msg)

Exception rethrown at [0]:

This is apparently an error that's been around for a while. It tends to happen when a DM is starting up (not sure if that's your experience) and an old element subscription is tried rather than initiating a new one.

Harmless apparently but it would be nice to see it handled more gracefully so we can avoid further questions or concerns about it.

I see, thanks for the explanation Simon

I’ll submit a feature suggestion so that it can be handled differently.
