PicorePlayer LMS Media scan terminated unexpectedly and then rescans randomly

Dear Forum,
i try to run LMS on Raspberry Pi 3 with picorePlayer, but i get an error every time i try to scan my library:
Database Optimize (1 of 2) Complete 00:05:37
Media scan terminated unexpectedly (Scanning Progress)
unfortunately LMS just starts to rescan the library randomly then, LMS gets unresponsive and i can't listen to my music.
I tried a complete reinstall of picore, but still the same.
Attached is the Scanner log file, i really hope that somebody can help me here again, having updated my Synology to DSM7 is a total nightmare:-(

Thank you
Pommes
