Summary0015837: Wi-Fi sync may not work correctly when another UPnP/DLNA client on the network is accessing MMW server at the same time
DescriptionToday we have been debugging why some playlists have only 500 tracks in MMA (based on Martin B. tests)
The issue was that at the time when MMW should return 500-1000 items interval of the playlist -- another client on the network (LG TV) requested another UPnP container and MMW returned incorrect result to MMA.
TagsNo tags attached.
Fixed in build1887

This is quite a long standing regression introduced by fixing 0010021, but hard to notice as it happens only for playlists with more than 500 tracks and only when another DLNA client is scanning MMW server extensivelly at the same time when MMA is downloading the playlist content.

Verified 1887 and confirmed same behavior in 2191

For tests I used combination of MMA/MMW/MM5/DLNA Browser and BubbleUPnP to stress test 1887 and 2191 accordingly while MMA is syncing.

Note: I also tested multiple sync clients at same time.
