I have 3 music libraries containing the same tracks, but at different bitrates. I normally add new tracks to the appropriate folders and immediately manually scan all 3 libraries. The scan for the first library starts, and normally the other 2 queue up and do their thing in order, but Sonic Analysis also starts when the first library is finished.
What’s started to happen is when Sonic Analysis kicks in, the scan for the next library hangs. I have to cancel the scan for the library it’s hung on, and then re-scan. This behavior started sometime in the last couple server updates.
