In Mac OS Mojove 10.14.5 with the latest stable server build...
If you exit Emby, you cannot restart it until a reboot.
With Emby active, all disks attached to my library tank speed wise. They go from 170+MB/s R/W to 60MB/s R/W. As soon as I close Emby they resume standard speed. This does not happen in windows or with other media services and creates a massive issue creating redundancy and other situations. It took me over 2 days to backup an 8TB disk. The same disk took 17 hours when Emby was closed.
Non-server related, Safari users still cannot edit metadata. Been like this for going on 4 months.
I will post logs in a minute when I reboot to get Emby up and running again. There shouldn't be any activity as I haven't been using Emby for my media.
