Brain Farts w/ Roon Nucleus

I have an original Roon Nucleus with a SSD drive in it.  Around 3GB of music.  Together with Tidal, Roon tells me that I have 2039 Artists, 4312 Albums, 61239 tracks, and 136 composers.  That is likely more than most users, but not as many as some of you, so I have read.
 

On a fairly regular basis, Roon has these brain farts moments, lasting 10-15 minutes, where I get the twirling Roon Icon and the system is shut down from playback.  It always eventually comes back. I don’t know the technical term, but I think it is a resort, reorganizing, re-something to the whole data base of music.  It always happens at the most inopportune time. Roon online forum has never come clean for me with an answer/fix.

I have revamped my Ethernet cabling and both the Roon Nucleus and the DAC/Streamer are mainlined, so I know it is not network drop outs.

I’ve read that others have had a similar problem, but never read a solution.  I have been looking into several angles to stop this.  (1) Upgrade to the Roon Nucleus Titan. (2) Checking out to see if some other Roon Ready Server is a better functioning piece of equipment, like the Innous.

I have two DACs/Servers in the house - BlueSound & dCS Lina - and they both have the same brain farts with Roon.  

I really like the functionality of Roon on the Nucleus.  My issue is not sound quality of Roon, it is the performance.  I must admit, that in all of my reading I have not been able to compare the functionality of a Roon Ready Innous vs. Roon Nucleus, or any other Streamer that folks mention here on the forum.

Any thoughts would be appreciated.  Thanks in advance.
