Sometimes Volumio doesn't play queue

Hello everybody

that is not a vital pb, but a little annoying and surprising.

But only sometimes (something like 1 per 50 tracks), Volumio plays not the next queue track, but a random one.

I read tracks on a local usb hfs+ HD with 2.175 version Volumio on a Raspberry Pi 3 (with a pifi pcm5122 dac), and I control Volumio trough wifi and Firefox on an El Capitan 8GB Ram 120GB SSD 2013 13" retina Macboopro.

I feel that this is not a very common pb…

just trying 2.185 version.

wait & see (listen)

Difficult to do anything unless you can catch the problem in logs, or narrow it down to particular tracks.
