This is a known issue. For me, it doesn't matter if I am trying to shuffle one album or an entire genre - it will freeze and crash the server. 

@Luke- is there an official thread or post that we can throw our support, like, or +1 to raise awareness for this issue?

Hi, we are looking into it. Thanks.
