Great that u could reproduce the bridge freezing issue.
Here I wud like to bring in your notice another similar issue.
After I run the ds with bridge continuously (the ds with bridge as input is power switched on continuously but i may not be playing songs from controller continuously) in every 2-3 days the bridge becomes inaccessible from the controller. The ds works as I can change the input to something else but bridge remains inaccessible. Only solution is resetting the bridge either from front panel or web interface.
I have used all different type of controllers - elyrics plug player, linn kinsky on ipad mini, bubble upnp on samsung tab4. Same result.
Any idea ?
