Sync problems with big music library

lanugo0815lanugo0815 Posts: 1Members Plex Pass

Dear all,
I am using Plex server quite a wile and I now upgraded to premium but I have problems getting my media onto my smartphone:

When I try to sync my comlete music libary with my phone the process works well until 50%. (8000 files left) After that the syc process gets really slow and breaks down every couple of files (10-50). Beside this the process drains a hell of battery. I have to constantly charge my phone. After several hours of constant clicking of the sync button I gave up

NAS: **Synology 216+ II with 2x 4 TB WB Black
**Mobile Device:
Samsung Galaxy S7 with 128 GB Micro SD Card Sandisk Ultra
Library: 90GB of musik mostly coded with 192/320kps resulting in 14.000 files in 1200 folders
Sync Option: No conversion

I also tried the following option
I my library into 3 pieces to lower the syc amout per libary. Now the problem occures at 70% with the same result.

Does anybody has a clue what the problem is or is Plex not able to handle such a big Database?

    i have pretty much the same problem but with a slightly different hardware setup.

    PC running Plex Server with i7, 16GB Ram, Plex Library on SSD, Data on 2x4TB WB Red
    Mobile Device: Currently Samsung Galaxy S7 but had the same issues with Sony Xperia Z3 Compact and a Galaxy J5 - all with 128 GB Micro SD
    Library: About 75GB in around 800 folders
    Sync Option: No conversion

    It is stuck now at 76% and every time i click on "Sync Now" its doing "Refreshing Information" but closes the process in the top task bar after a few seconds.

    Any help is highly appreciated

    I'm also having a similar issue. Big MP3 playlist that I want to sync. All MP3's are there. But it is not saying 100%.
