Over the last several versions when I add new movies and plex picks up on scan it seems the scan never stops. I’ve left if for days and it keeps spinning. Looking at the log today I see this which seems like it could be a problem.

Something probably did get corrupted in Sync.
Sync has been problematic and engineering is spending some serious effort on it right now.
That’s all I’m allowed to say about what they’re doing but from what I read, it looks good.
Scans running forever usually indicate media didn’t match -OR- you have ‘automatically detect changes’ and something is writing in one of the directories which PMS is monitoring. (most common cause)
I’ve never run into this constant scan issue until the last few updates. If there wasn’t a match it should give up not get hung. As for something accessing the directory plex is watching, doubtful. The file path on the nas is only used for plex. Would the logs narrow it down?
Your database is fragmented all to heck. It keeps scanning because it never finished what it started.
It can’t add more because it can’t get that far.

After that completes, Settings - Server - Scheduled Tasks. Make sure database optimization is enabled.
That Atom CPU is not the fastest thing so you really have to keep on it for optimization.
It’s always been on and I typically do the manual optimize anytime I add a substantial amount of video or remove any. Is that all you see wrong? I should just let it ride itself out and it will be caught up?
