I try to sync my whole library (about 9000 songs) from MM to my iPhone 6, 128 GB, iOS 8.3 for weeks but it always fails. The full sync stops randomly, sometimes at 7000+ songs, sometimes at 500. The error messages are not always the same but similar and always related to MediaMonkay64Helper.exe. The most recent one was:
Exception EAssertionFailed in module MediaMonkey64Helper.exe at 000000000014BB59.
Unknown function: AFCFileRefClose (C:\projects\Plugins\Devices\d_iPod\x64Helper\x64Caller.pas, line 338)
Sometimes even my iPhone seems to restart on sync failure, as it calls for PIN with the information that this "is required after a restart" or something.
I got it working once by splitting up the whole lib in several playlists, each having less than 3000 songs, and syncing just these playlists one after the other (not the whole lib at once). That worked one time. But I would like to sync the whole lib at once and not in steps with dumb playlists I do not need...
I tried several things to analyse or fix the problem: it shows up on two machines (desktop@win7x64 and notebook@win81x64). I tried to empty the iTunes_Control folder on my phone. I tried differnet MM versions. All to no avail. And I am now heading for a debug log for the problem:
With a MM default install I could not get any abnormal information in the debug view. It simply stops with
Code: Select all
iPhone: Got Device Grappa Data (Length: 83)
I would appreciate any hints to get to the root cause of the problem...
Thx a lot,
