Importing large RB database into prime 4+ ssd causes restart loop (v4.3.1)

I have been trying to import around 150,000 tracks analyzed and exported from RB into the internal ssd of my Prime 4+, when it’s almost done with the analyzing the device reboots and asks me to do the import again and the same thing happens over and over. My entire library is around 3tb so I keep it on my external Qnap Thunderbolt NAS, all my music in rekordbox and iTunes can be accessed from the NAS. As some of you know, Engine Desktop doesn’t support network drives, so therefore I had to figure out a way to get all my RB playlists and folder structures into Engine Desktop. It’s was a ton of work but this is how I managed to do it, using RB, Engine Desktop and Lexicon DJ.

  1. Back up your RB library before you begin!
  2. Copy your music files from the NAS to your Prime 4+ internal ssd
  3. Move your RB master library to the internal ssd of your Prime 4+ and close RB
  4. Import all your RB music or playlists into lexicon DJ, you should now see your entire RB library or Playlists in Lexicon, close Lexicon.
  5. Eject your NAS
  6. Open Lexicon try to play any of your files and the exclamation sign should appear stating that the file is not found.
  7. Select all your music files, right click and select relocate, select the folder where your music is located in your prime 4+ internal ssd, Lexicon will look for the files in the new location and fix the paths for you. (RB auto relocate feature took forever, Lexicon did it in less than 5 mins)
  8. Check that the newly fixed files are working
  9. Export back the entire library or playlists to RB from Lexicon, close Lexicon
  10. In RB check that the files play correctly
  11. Export your RB library XML to the location of your choosing, close RB
  12. In Engine Desktop import the RB Library XML, now all your music and playlists should display and work correctly
  13. Import all the files to your Collection, let the analyzing complete
  14. Eject it and voila, insert the internal SSD back into your Prime 4+ with no crashes
  15. You can return your master RB file back to its original location (step 3) If any issues with your RB library happen you should have the backup file created in step 1

I still haven’t been able to figure out what causes the restart loop when the import is being done in the Prime 4+ (the same internal ssd used above was used to export from RB to the ssd the into the Prime 4+)

Great find! I recently bumped into the same issue for a friend of mine. The device rebooted at a certain point when importing, always. In his case, we pinned it down to the last tracks he added to his drive and removed the tracks. After that everything went fine, so my best guess would be it has something to do with a file somewhere which gets corrupted. It would be awesome if there was a log which track is causing the crash, but afaik there is no log available.

yeah it was impossible for me to find out and there are to many tracks and playlists to go over one by one. Lexicon does have a find broken tracks feature that I tried and I did remove and fix some, but the loop still kept happening.

So I had to to do all this work around and do everything in Engine Desktop and then transfer it all analyzed in ED into my internal ssd.

also my biggest issue was the location being in a NAS without ED support it, hopefully they will add this soon.
