MinimServer 2 on Synology: Format Error

[LittleScarabee]

Hi All,

I identified (I think) a strange functioning, by using default configuration in MinimServer 2 :
* I identified it's necessary, via Web Interface, to click on button "rescan" to be able to see again MinimServer in Bubble UPnP, otherwise I did not saw it. After click on this button I can saw "Restarting".
NOTE : I cannot do this action : restart or rescan via MinimWatch. The background of the icon still in "gray", that means : no server available if I am right.

Two questions :
1 / Is it normal when we click on "rescan" the service restarted ?
2 / Is there any sleep "mode" in MinimServer 2 after several hours of non-uses ?

Thanks
