MinimServer 0.8.2 update 40 temporarily shows error message

[DavidHB]

On applying update 40 to the MinimServer installation on my ReadyNAS, error messages were generated, as shown in the following log sequence:

As can be seen, restarting seems to have removed 2 of the 3 error messages, and then the third message did not appear after a rescan. So the problem seems to be resolved. Do the error messages have any particular significance?

My Windows installation of MinimServer did not produce any errors when update 40 was applied.
