Roon isn't stable and they edit their forum to hide it

Fact is Roon by its nature is a somewhat complex beast for the average person to get a handle on.  Definitely not plug  n' play.  That adds to teh # of issues or difficulties that people report.  Some may be Roons fault but others just chalk up to inexperience with the product or learning curve.  

I work with complex computer systems for a living so I have some experience in this area.  

Most things worthwhile are not necessarily easy.   Audiophiles know that.   That includes Roon.   

It's not hard to get started but there is so much that can be done it can become quite complex as you do more. 

I would expect to see a certain amount of user angst, especially from those who are less technical or not really up on modern technology.

Live and learn!  Roon is worth it.  The more you learn the more benefits reaped. 

I’m a Roon lifer.  I joined about 4 years ago.  I’ve had my share of problems but they have all been about Windows, not about Roon. My only disappointment with Roon is their support model.  It depends on helpful users.  I don’t know what motivates the wonderful folks who make themselves available to help users resolve their problems, but I am grateful to them.  I wish there was phone support like Apple provides, but I expect the cost would be prohibitive!

I've been a lifer with Roon since the beginning.  No problems with 12K+ albums with the core on a QNAP NAS, but Roon ARC freezing on an iphone has been a wreck and not worth endless deletion and reload of the phone app to restore operation.  I'm back to youtube on the phone. 

A couple of thoughts here, for whomever it may help - I find it best not to mix tracks from different services when building playlists on Roon. It gets quite wonky after a hundred or so tracks from say tidal and qobuz on the same playlist, but the one or two odd things begin to happen right after 45 to 50 tracks. As such, I avoid it altogether, and keep playlists service dedicated.

Also, roon does reboot on its own every half hour or so in my system, but that has never affected playback, and my queue goes on uninterrupted, while Roon comes back on line the moment I reaccess it.

Aside from these little hiccups, Roon has served me unfailingly the past three years or so. And, as with everything else in our hobby, your mileage may vary.

I use rips from Synology NAS, streams from both Tidal and Qobuz, Roon radio stations, have library along line so 12k albums and never have issues. Again, I suspect OP has some kind of OS issues causing conflict.

@jji666  Curious as to whether you using analyzers in Roon setup? These may take up much processor resources. I go along with Taiko suggestions and turn both analyzers off, minimally try them throttled.
