Generated a static playlist from my auto playlist that always failed. That playlist was 1200+ tracks. I reduced that to 400 ovdr several iterations. I am 100% confident that this is a MMW time out issue. There needs to be some mechanism to keep MMA from timing out when MMW takes too long.

I wasn't able to sync with 128 but sort of can now with 130..

A few issues though

1. the first attempt always fails with a synchronization fail dialogue. It works if I try a 2nd time
2. When I'm presented with a delete songs box and click yes the box does not go away , but it looks like it deleting and then downloading in the background. If i click yes or no a second time it crashes and sends logs.
3. After rebooting it looks like my playlists get all messed up and will drop to 5 to 10 songs. Its not everytime, but the only real fix is to delete the playlist from MMA and resync.

The good news: It does not crash anymore.
The bad news: It times out and says the sync failed because it cannot connect...

Keep up the good work!

Wifi sync is fixed in 130.

However, it still times out if the file set is too large (or at least that's my interpretation of what's happening). I have several playlists that I have set to sync in USB that work fine. If I select the same set for wifi, it fails. I ran DebugView and can see that MMW is still building the file set when MMA says "failed". If I remove the largest playlist, MMW finishes quicker and the sync begins correctly. If this is a problem with timing out of the server, perhaps a keep alive signal should be sent every xx seconds to tell MMA that it's still working. Just a thought.

For reference, it takes 31 seconds for DebugView to finish displaying activity after selecting "sync now" in MMA however MMA displays the "sync failed" message after 20 seconds.
