Roon is stuck importing music with "X" amount of files remaining [Resolved B247]

Hi,

I have a problem which seems to have occurred to others before, but reading the threads isn’t very enlightening as to what the cure might be and none are recent.

System is latest ROCK, Version 1.0 (build 76) stable, with Server Version 1.3 (build 242) stable. Hardware is standard NUC 7i7BNH, 8GB RAM and 120GB SSD (91% free space). Everything wired Ethernet apart from iPad Remote of course. No LAN extenders or other dodgy hardware. Music stored on two Synology NAS.

The last similar thread seems to be this one:
Stuck adding music to library, some tracks still lack to be identified [Solved] , but that seems to contain two issues.

I updated to the latest ROCK build yesterday and since then I have had the spinning icon with the following showing:

A full rescan of my watched folders was triggered by the update and that is the result. It picked up around 600 tracks and was left with these 10.

This did happen once before on the original release build of ROCK at one point, but it resolved itself overnight that time with no clues as to what caused it.

So far I have done the following:
Restarted the Roon Server software twice to try and clear it (via the web interface) but with no change.
Toggled Off/On both Background Audio Analysis Speed and on Demand Audio Analysis Speed, with no change.
Cleaned the Library (I do this regularly anyway).

I have not powered off ROCK yet for a full restart, but really should not have to do this with an ‘appliance’.

If I could identify the 10 ‘stuck’ tracks that would help, but I have a fair number of tracks not imported due to being corrupt etc, but this should not cause Roon to get stuck in this way as all of them have been known about/identified as ‘Skipped Files’ since I first installed Roon for the 14 day trial.
When transferring files to the NAS, I am careful to exclude any characters which might trip up Roon, but these should just result in an exclusion rather than cause it to get stuck.
