It says it’s scanning but it’s not.

I’m using the app.plex.tv. It says this:

Sonic Analysis:  
Processing 5789 albums

But nothing is happening.

Not great at reading logs, but can I ask where are you seeing the analysis is happening?  
More importantly what makes you so sure it isn’t happening?

Seemingly from what I have read it takes several days in some cases.

It said:

all weekend. But the logs say 0.0% done.

It’s just broke for me.

Your log is merely covering 10 minutes. During this time the server is busy scanning a music library.  
Sonic analysis will be performed after all the other jobs under Scheduled Tasks are done, because it is the most expensive operation.

You might wanna disable “Update all libraries during maintenance” for a few weeks. And maybe also disable “Scan my library periodically” for a while.

I did what you suggested. It says

PLEX PC

Dashboard

Sonic Analysis:  
Processing 5800 albums

But no CPU activity.
