isn't a valid object

[entdgc]

Hi,

Occasionally I see output like the following from MINIWATCH PROPERTIES...

Code:

MinimServer 0.8.4.5 update 104, Copyright (c) 2012-2017 Simon Nash. All rights reserved.
MinimStreamer 0.6.4, Copyright (c) 2012-2017 Simon Nash. All rights reserved.

starting MinimServer
MinimServer is running
MinimServer: 0$=Artist$21805 isn't a valid object
MinimServer: 0$=Artist$22932 isn't a valid object
MinimServer: 0$=Artist$17047 isn't a valid object
...

I have never heard or seen any problems but the 'isn't a valid object' is interesting. I have never been able to trace what action causes this. My server is running on a QNAP TS251 - fully up to date.

Any thoughts...?
