Maximum songs (music)

How many songs (music) can Serviio handle.
I now have 13916 songs in Serviio, but I want more songs in Serviio but he doesn't work anymore, he's not doing anything?

Just over 96000 tracks here with no issues - running on a QNap TS473a with 32GB of RAM...could it be the Java process in your case is just out of available RAM?
